Abstract
Isomeric polymers [Cd2(mbt)4] n and [Cd(mbt)2] n (mbt = mercaptobenzothiazole) are investigated. The complex {[Cd(μ-η2-C7H4NS2)2][Cd(μ-η2-C7H4NS2) (μ-η3-C7H4NS2)]} n is formed by the reaction of Cd(NO3)2·4H2O with 2-Hmbt in the presence of H2biim in EtOH/H2O. The complex crystallizes in the orthorhombic space group Pca2(1), where a = 21.892(2), b = 9.8994(11), c = 14.8687(15) A, α = 90, β = 90, γ = 90o, V = 3,222.3(6) A3, and Z = 4. The two Cd atoms, one exhibits a CdN2S2 tetrahedral geometry and the other exhibits a distorted CdN2S3 trigonal bipyramidal geometry, are linked by bridging–chelating mbt and bridging mbt ligands. The infinite 1D polymer chains complex {[Cd(μ-η2-C7H4N2S2)2][Cd(μ-η2-C7H4NS2) (μ3-η2-C7H4NS2)]} n is formed by the reaction of Cd(NO3)2·4H2O, 2-Hmbt in the present of H2biim, which contains a CdN2S2 tetrahedral geometry and a distorted CdN2S3 trigonal bipyramidal geometry.
