Pyrrolidinedithiocarbamate nickel(II) complexes with l,4-bis(diphenylphosphino)butane of composition [Ni(plddtc)(dppb)]X . H2O and [Ni2(plddtc)2(NCS)2(dppb)] 2H2O (pld = C4H8; dtc = S2CN-; dppb = l,4bis(diphenylphosphino)butane; X = Cl, Br, I, NO3, ClO4) have been synthesized. The compounds have been characterized by elemental analyses, IR and electronic spectroscopies, thermal analysis, magnetochemical and conductivity measurements. [Ni(plddtc)(dppb)]I · H2O complex was studied by means of a single-crystal X-ray analysis. Crystals are orthorhombic, space group Pnma, with a = 20.061(4), b=16.052(3), c= 10.578(2)Å, V= 3406.3(11)Å3 Z = 4. The nickel(II) atom is coordinated by two phosphorus atoms from the dppb ligand [Ni-P = 2.1971(13)Å] and by two sulfur atoms from the pyrrolidinedithiocarbamate anion [Ni-S = 2.2151(13)Å] in a distorted square-planar arrangement. The iodide anion [Ni-I = 5.0476(13)Å] and the water molecule [Ni-O = 7.163(13)Å] are not bonded to nickel. |
