Abstract

[Ni(mdtc)(1,3-dppp)]ClO4 (1), and [Ni(mdtc)(1,4-dppb))ClO4 (2) [(mdtc(-) = 4-morpholinecarbodithioato anion. 1,3-dppp = 1,3-bis(diphenylphosphino)propane, 1.4-dppb = 1.4-bis(diphenylphosphino)butane)] have been prepared from their parent dithiocarbamate. The planar complexes were characterized by electronic and IR spectra. Single crystal X-ray structures of compounds 1 and 2 were determined. Both the complexes have planar NiS2P2 chromophores in keeping with the observed diamagnetism. Ln complexes 1 and 2 the Ni-S and Ni-P distances are symmetric. The thioureide C-N distances of both the complexes show a decreasing trend compared to the C-N distance in the parent Ni(mdtc),. The resulting P-Ni-P angles are higher in both the complexes (96.5(1)degrees in 1. 101.4(8)degrees in 2) due to puckering of propane and the butyl alkyl chain associated with 1,3-dppp and 1,4-dpppb.
