Poly[μ2-aqua-aqua-[μ3-N-butyl-N-(2-hy-droxy-ethyl)di-thio-carbamato-κ(3) O,O':S]sodium].

ABSTRACT: In the title compound, [Na(C7H14NOS2)(H2O)2] n , the Na(I) cation is coordinated by five O atoms [Na-O = 2.3142 (11)-2.4677 (10) Å] from three aqua and two N-butyl-N-(2-hy-droxy-eth-yl)di-thio-carbamate (L) ligands and one S atom [Na-S = 3.0074 (6) Å] from a third L ligand in a highly distorted octa-hedral geometry. Two aqua ligands related by an inversion center bridge two Na(I) cations, and each L ligand coordinates three Na(I) cations, leading to a layered arrangement aligned parallel to the bc plane. Inter-molecular O-H⋯S hydrogen bonds are observed in the inner part of each polymeric layer; these are packed along the a axis and held together by weak van der Waals forces.

Project description:The asymmetric unit of the title complex, {[Cd2(C10H10N3O3S)2(C10H8N2)(NO3)2]·4C3H7NO} n , consists of one Cd(II) cation, one N-[2-(2-hy-droxy-benzo-yl)carbamo-thio-yl]acetamidate ligand, half a 4,4'-bipyridyl ligand, one coordinating nitrate anion and two di-methyl-formamide solvent mol-ecules of crystallization. The bipyridine ligand is completed by inversion symmetry. The metal cation exhibits a distorted penta-gonal-bipyramidal coordination geometry provided by two O and one N atoms of the thio-semicarbazide ligand, two O atoms of the nitrate anion, one S atom of a neighbouring thio-semicarbazide ligand and one 4,4'-bi-pyridine N atom. The bridging role of the thio-semicarbazide ligand through the S atom leads to centrosymmetric binuclear units, which are further linked by 4,4'-bi-pyridine units, forming polymeric chains extending along the b-axis direction. An intra-molecular N-H⋯O hydrogen bond occurs. The crystal structure also features N-H⋯O and O-H⋯O hydrogen bonds, leading to the formation of a three-dimensional network.

One of the tert-butyl groups is disordered over two positions with a site-occupation factor of 0.834 (6) for the major occupied site.

N-Ethyl-2-[1-(2-hy-droxy-4-methyl-phen-yl)ethyl-idene]hydrazinecarbo-thio-amide.

Project description:The title compound, C12H17N3OS, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the benzene ring and the hydrazinecarbo-thio-amide group are 6.9?(4) and 37.2?(5)° in mol-ecules A and B, respectively. An intra-molecular O-H?N hydrogen bond is observed in each mol-ecule. This serves to maintain an approximately planar conformation for mol-ecule A, but leaves a significant twist between these two groups in mol-ecule B. In the crystal, a weak N-H?S inter-action is observed, forming inversion dimers among the B mol-ecules and resulting in an R 2 (2)(8) motif. These dimers are further inter-connected by weak N-H?O and C-H?O inter-molecular inter-actions, forming chains along [011].
