The X-ray crystal structures of the cadmium complexes of pyridine-1-thiol and mercaptobenzothiazole, [cd(C5H4NS)2]n And [Cd(C7H4N2S2)2]n: Two unusual volatile polymeric complexes

Electrochemical Synthesis and Structural Characterisation of Cadmium and Mercury Complexes Containing Pyrimidine‐2‐thionate Ligands

“…Three of the four Cd-S bond lengths are very similar and are in the range 2.6347 (12) [39,40] However, the range for these distances in the complex [Cd(pyS) 2 ], [41] which has a similar chain structure, is much wider [2.543(5)-3.038(4) Å].…”

“…Thus, while the complex with pyridine-2-thione consists of [Cd(pyS) 2 ] x , [41] a polymeric chain structure, the increased steric constraints introduced by the methyl groups in the case of 4,6-dimethylpyrimidine-2-thione reduce the tendency for polymerisation and the complex obtained is hexanuclear [Cd(4,6-Me 2 pymS) 2 ] 6 . [35] The metal atom in the latter complex is hexacoordinate as in [Cd(pyS) 2 ] x .…”

“…[35] The metal atom in the latter complex is hexacoordinate as in [Cd(pyS) 2 ] x . [41] A higher degree of steric hindrance, such as in 3-trimethylsilylpyridine-2-thione, produces a dimer [Cd(3-Me 3 Sipyt) 2 ] 2 , [45] with each cadmium atom in a five-coordinate environment. In the case of 4-trifluoromethylpyrimidine-2-thione, the presence of a CF 3 group in the 4-position produces greater steric hindrance than in pyridine-2-thione, but less hindrance than in 4,6-dimethylpyrimidine-2-thione.…”

Crystal structure of 1-azonia-1-(2-mercaptobenzothiazolyl)ethyl-2- thiolato-1,3-benzothiazole, C16H12N2S4

“…The 1,3-benzothiazole-2-thiolate (hmbt) is aversatile ligand with more than one donor atom and many of its complexes have been synthesized [5,6]. From hmbt, the inner salt of a new flexible multidentate ligand containing Nand Satoms has been synthesized.…”

Bis(1,3-benzothiazole-2-thiolato-N,S')(2,2'-bipyridine-N,N')cadmium(II)

“…Although extensively studied by spectroscopic methods, crystallographic investigations of zinc and cadmium complexes of this ligand have been limited (McCleverty et al, 1982;Hursthouse, Khan, Mazid, Motevalli & O'Brien, 1990). We have recently reported the synthesis of the complexes [M(C7H4NS2)2(py)2], [M(C7H4NS2)2(2,2'-bpy)] and [M(C7HaNS2)2(phen)] (py = pyridine, phen = phenanthroline, bpy = bipyridine, M = Zn or Cd) and the single-crystal structures of [Zn(C7H4NS2)2(py)2], [Zn(CTH4NS2)2(2,2t-bpy)] and [Cd(C7H4NS2)2(py)2] (Baggio, Garland & Perec, 1993).…”
