Bis(2-amino-5-methyl-1,3,4-thiadiazole-κN ³)dichloridocobalt(II)

Abstract

Key indicators: single-crystal X-ray study; T = 296 K; mean (C-C) = 0.006 Å; R factor = 0.045; wR factor = 0.110; data-to-parameter ratio = 20.5.In the monomeric title complex, [CoCl 2 (C 3 H 5 N 3 S) 2 ], the Co II atom is tetracoordinated by two chloride anions and two N atoms from two monodentate 2-amino-5-methyl-1,3,4-thiadiazole ligands, giving a slightly distorted tetrahedral stereochemistry [bond angle range about Co = 105.16 (12)-112.50 (10) ]. In the complex, the dihedral angle between the 1,3,4-thiadiazole planes in the two ligands is 72.8 (1) . There are two intramolecular N-HÁ Á ÁCl interactions in the complex unit, while in the crystal, intermolecular N-HÁ Á ÁN and N-HÁ Á ÁCl hydrogen bonds link these units into a twodimensional layered structure parallel to (011).

Synthesis and Crystal Structure of Anickel (II) and Zinc (II) Complex From 1,5-Bis [(2-Thiophenyl) Methylidene] Thiocarbonohydrazide

“…In the course of our studies on the chemistry of transition metal compounds, we have prepared and characterized a number of chelates containing N and O donor sites [11][12][13][14][15]. Considerable interest is accorded to the development of multidentate ligands containing different binding sites such as N, O or S [16,17]. Herein we present a structurally characterized nickel(II) and zinc(II) complexes synthesized from potentially heptadentate Schiff base ligand.…”
