Three amidine-based ligands were used in the crystal design of a series of mononuclear Zn(II) complexes. Interaction of zinc chloride, ZnCl2, with N-2-pyridylimidoyl-2-pyridylamidine (Py2ImAm) resulted in complexes [Zn(Py2ImAm)2] (1) and [ZnCl2(Py2ImAm)] (2). In [Zn(Py2ImAm)2] (1, monoclinic, P21/c), the metal ion was coordinated with the bidentate pocket of the anionic form of Py2ImAm, while in [ZnCl2(Py2ImAm)] (2, monoclinic, P21/n), the tridentate coordination to a neutral Py2ImAm was completed by two chloride anions. This structural variation was achieved by a pH-controlling strategy using the weak base triethylamine (TEA). Otherwise, three ionic complexes were obtained with 2-amidinopyridine (PyAm) and Zinc(II), [ZnCl(PyAm)2]Cl (3, triclinic, P-1), [ZnCl(PyAm)2]2[ZnCl4]·C2H5OH (4, monoclinic, P21/n), and [ZnCl(PyAm)2]2Cl·CH3OH (5, triclinic, P-1). They comprised the same [ZnCl(PyAm)2]+ monocation with a butterfly-like shape provided by the bidentate chelate coordination of two PyAm neutral entities and a chloride ligand. In a similar butterfly shape, ionic complex [ZnCl(PmAm)2]2[ZnCl4] (6, monoclinic, C2/c) comprised the mononuclear [ZnCl(PmAm)2]+ cations with two bidentate chelate-coordinated 2-amidinopyrimidine (PmAm) as neutral ligands. The Zn(II) pentacoordinated arrangement in 3–6 was variable, from square pyramidal to trigonal bipyramidal. The reported compounds' synthetic protocols, crystal structures and photoluminescence properties are discussed. [ABSTRACT FROM AUTHOR]

Introduction: Currently diabetes is a great challenge for society and health systems, the phenomenological approach is configured as an essential method to reconstruct experiences and meanings of those living with Type 2 Diabetes (T2D). Objective: To analyze the qualitative scientific literature with phenomenological method on the experience of living with T2D in adults. Methodology: Systematic review according to the PRISMA statement, 8 electronic databases were con-sulted using the terms MeSH and DeSC, phenomenological studies in Spanish, English and Portuguese published from 2012 to 2022 were included. Results: out of 776 studies, 15 phenomenological studies showed the experience of living with TD2 on: unexpected diagnosis and lifestyle changes, knowl-edge, and attitude towards TD2, spirituality, self-care, cultural education, relationship between health pro-fessionals, financial burden and social support. Conclusion: People with TD2 experience diverse situations that require more phenomenological research to understand them and to propose care strategies with interventions adapted to each context, allowing the dialogue of knowledge between the person with TD2 and nursing.

Objective: To understand the experience of self-care of the elderly person in the post-pandemic transition COVID-19. Method: Qualitative phenomenological study, conducted in a city of Mexico, from March to December 2021. The sample was intentional with 8 participants, determined by the criterion of information saturation. Inclusion criteria were: men and women aged 60 years or older, linked to elderly community groups. Data analysis: carried out through the hermeneutic circle: Pre-understanding, Understanding and Interpretation. All participants gave their informed consent. Results: The testimonies allowed us to apprehend six themes: Protective measures and physical care; Awareness of being an elderly person; Care in the face of the infodemic; Being cared for by the family and caring for the other; Learning after the pandemic; Self-care present in the lived experience of the elderly person. Conclusion: The elderly person transits the tempo-rality of their care, and cannot be separated into a before and after, but rather, an understanding of being an elderly person in self-care throughout a phase of learning and internalization of one's own care.

Introduction: Despite the care need expressed by older adults, sexuality is a human dimension that is hardly addressed by Health Sciences. Objective: To describe the meaning of older adults' sexuality based on the influence exerted by the world and the body. Method: A phenomenological study guided by the concepts of Merleau Ponty's Phenomenology of Perception, conducted in a city from central Mexico with groups of older adults. Intentional sampling with the following selection criteria: older adults with preserved verbal communication ability, with no cognitive decline (=24 points in the Mini-Mental State Examination), and with legal decision capacity; the participants were 16 older adults, considering the data saturation criterion. Virtual phenomenological interviews were conducted, analyzed according to Giorgi's phenomenological method. The ethical and qualitative rigor criteria were respected. Results: Three topics emerged from the units of meaning identified, namely: 1) The world as experienced by older adults; 2) Possibilities of the current body; and 3) Stereotypes and preconceptions about older adults' sexuality. Conclusions: Older adults' sexuality is influenced by the context where they interact and by the experiences underwent in this aspect throughout their lives. Diseases and physical limitations affect aged people's sexuality and hinder its expression; in this same sense, the stereotypes and preconceptions about sexuality existing in society and in the family condition sexual expression and force older adults themselves to repress their sexuality.

Objetivo. Reflexionar en el momento de cuidado como un encuentro fenomenológico entre enfermera y persona cuidada a la luz de la teoría de Jean Watson. Metodología. Se trata de una reflexión teórico-filosófica a partir de la referencia de momento de cuidado de Jean Watson y la perspectiva de otros autores sobre el objeto. Resultados. La enfermería como disciplina acoge el concepto de cuidado humanizado como una forma de expansión del ser a través del encuentro fenomenológico de dos personas, una persona que cuida y una que está siendo cuidada. Este encuentro se conoce como momento de cuidado, donde se enlazan las formas más supremas de sanación. Conclusión. La enfermera como persona que cuida se encuentra con una persona que es cuidada a través de un encuentro transpersonal que debe ser único, donde sus historias de vida convergen para dar paso a un momento de cuidado que es capaz de armonizar cuerpo, mente y espíritu.
