A flexible octadentate C-shaped bis(salamo)-based ligand (H4L) with two different coordination environments, which can react with different metal salts to form heterotrinuclear zinc(II)-lanthanide(III) bis(salamo)-based complexes [Zn2La(L)(µ2-OAc)2(η2-NO3)]·2CH2Cl2 (1) and [Zn2Ce(L)(µ2-OAc)2(η2-NO3)] (2). The detailed analysis of Hirshfeld surfaces and fingerprints compares the intermolecular interactions, which are very important for the construction of different supramolecular structures. The molecules are connected by the combination of C–H···O hydrogen bonds to form an infinite 1D supramolecular chain. [ABSTRACT FROM AUTHOR]

One new polymeric cadmium(II) complex {[Cd(bdmpe)(µ1,5-dca)]ClO4.CH3OH}n has been synthesized by the reaction of cadmium perchlorate with ligand N,N-bis((3,5-dimethyl-1H-pyrazol-1-yl)methyl)-2-(phenylthio)ethan-1-amine (bdmpe) in presence of dca (dicyanamide, N(CN)2-) as bridging ligand in methanol and characterized by spectroscopic techniques. Single crystal X-ray diffraction study of the complex confirmed that it has polymeric 1D chain and each cadmium centre has distorted octahedral geometry with N5S coordination and is bonded through two terminal nitrile group of the dca ligand using µ1,5 coordination modes. Intermolecular interactions and packing modes of the compound are described by Hirshfeld surface analysis and two dimensional finger print plots. [ABSTRACT FROM AUTHOR]
