Abstract
Single crystals of [Cu(ATSC)]NH 2SO 3 (1) (ATSC -4-allylthiosemicarbazide) were obtained by electrochemical synthesis using alternating current. Compound (1) crystallizes in P2 12 12 1 sp. gr., a = 6.8284(2), b = 9.3054(3), c = 16.1576(11) Å, Z = 4. ATSC moiety acts as tetradentate ligand, chelating two symmetrically related copper atoms. The Cu atom possesses trigonal pyramidal coordination, formed by two sulphur atoms (one of them at the apical position), nitrogen atom and C=C bond. Sulfamate anion is associated via hydrogen bonds. By slow hydrolysis of 1 crystals of [Cu 2(ATSC) 2]SO 4 (2) were obtained: P1 sp. gr., a = 9.526(2), b = 12.687(2), c = 14.7340(10) Å, α = 95.119(10), β = 89.903(12), γ = 109.113(14)°, Z = 4. The asymmetric unit of 2 contains two formula units, which are related by pseudosymmetry via a glide plane a. One half of four ATSC molecules act as in 1, the rest as tridentate ligands, which coordinate the two copper atoms in apical positions with sulfate anions. This Cu-S coordination was to date unknown. The structure of the ATSC ligands contributes to the unexpected competitiveness of C=bond in the coordination sphere of Cu I inspite of strong donor atoms. © WILEY-VCH Verlag GmbH, D-69451 Weinheim, 2001.
