The title polymeric compound, {[MnHg(SCN)4(H2O)]-C4H8O2S}n, consists of slightly distorted MnN4O2 octahedra and HgS4 tetrahedra. Each MnII ion is bound to N atoms belonging to the thiocyanate (SCN) groups and to two O atoms of adjacent water ligands. The sulfolane molecule connects with the coordinated water molecule through hydrogen bonding. Each HgII atom is coordinated by four SCN S atoms. The two adjacent MnII atoms and two O atoms of bridging water molecules connect with one another and form a parallelogram. Each pair of MnII and HgII atoms is connected by an -SCN- bridge, forming an infinite three-dimensional structure. [ABSTRACT FROM AUTHOR]

Pairs of Cd atoms are bridged by two water molecules, forming a parallelogram, and each water molecule is hydrogen bonded to a sulfolane molecule. Pairs of Cd and Hg atoms are connected by —SCN— bridges, which leads to the formation of a three-dimensional —Cd—NCS—Hg—network. [ABSTRACT FROM AUTHOR]

The [Cu(dmit)2]2− anions and tetraethyl­ammonium counter-cations form a layered arrangement in the crystal structure. [ABSTRACT FROM AUTHOR]

The title compound, C13H18O2S5, possesses twofold symmetry and is composed of two pivalyl groups lying on opposite sides of the planar 1,3-di­thiole-2-thione conjugated moiety.

In the crystal structure, there are no significant intermolecular hydrogen bonds. [ABSTRACT FROM AUTHOR]

The title compound, C15H11ClN2S, has been prepared by the reaction of Lawesson's reagent with N-(2-chloro­benzoyl)- N′-(4-methyl­benzoyl)­hydrazine, under microwave irradiation and in the absence of solvent. It crystallizes with two mol­ecules per asymmetric unit and X-ray analysis reveals that the three rings in both mol­ecules are nearly coplanar. The mol­ecules form stacks, in a head-to-tail manner, with intermolecular π–π interactions. Intermolecular C—H⋯N hydrogen bonds are also present. [ABSTRACT FROM AUTHOR]

The central 1,3-dithiol­ane-2-thione fragment of the title compound, C15H10O4S7, is planar; the conformations of the phenyl­sulfonyl­thio substituents in positions 4 and 5 of the dithiol­ane ring are related by an approximate twofold axis coinciding with the C=S bond of the 1,3-dithiol­ane-2-thione group. The planes of the phen­yl rings form dihedral angles of 25.4 (4) and 31.1 (4)° with the least-squares plane of the central dithiol­ane ring. [ABSTRACT FROM AUTHOR]

The title complex, C6H15N4O2+·C4H3O4−·2H2O, contains a planar ring formed by sharing one H atom between the O atoms in the carboxyl groups of the maleate anion. This hydrogen bond is slightly asymmetric. In thel-argininium(+) cation, both the α-amino and the guanidyl groups are protonated. The nonlinear optical response of the compound is derived from the intrinsic hyperpolarizabilities of thel-argininium cations, maleate anions and intermolecular hydrogen bonds.

The title compound, C23H22Cl4N2O2, was synthesized by the reaction of 1,1′-spiro[4,4]nonane-1,6-diamine and 3,5-dichlorosalicylaldehyde. It is a new Schiff base containing a spirocyclic backbone and an approximate non-crystallographic C2 axis. Two intramolecular O—H...N hydrogen bonds determine the relative orientation of the two benzene rings. Intermolecular π–π stacking interactions between the phenyl rings and weak intermolecular C—H...Cl hydrogen bonds stabilize the structure. Cp1 and Cp2 are the centroids of the planes defined by atoms C11–C16 and C18–C23. The angle between the planes is only 0.8° and interplanar distances are Cp1...Cp2( x, y, z + 1) = 4.023 Å and Cp1...Cp2( x + 1, y, z + 1) = 4.032 Å. [ABSTRACT FROM AUTHOR]
