Özet

Benzyl(4-methoxyphenyl)dithiophosphinic acid (HL) was obtained as solid and was treated with the NiCl(2)6H(2)O, CoCl(2)6H(2)O, ZnCl2, and CdCl2 to prepare its Ni(II), Co(II), Zn(II), and Cd(II) complexes. The nickel complex was further treated with pyridine which led to the formation of octahedral dipyridine derivative. HL was obtained through the addition reaction of the perthiophosphonic acid anhydride Lawesson reagent, (LR), [2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide], with the corresponding Grignard compound (benzylmagnesium bromide) in diethyl ether medium.The complexes were all of the stoichiometry of [M(L)(2)](x), with x = 1 for M = Ni2+ and x = 2 for M = Co2+, Cd2+ and Zn2+. The coordination geometry was square planar in the nickel(II) complex and tetrahedral in the others. Similar to many other nickel(II) complexes, the Ni(L)(2) reacts reversibly with pyridine to yield the octahedral complex ({(Py)(2)Ni(L)(2)}).The compounds were characterized by elemental analysis; MS, FTIR, and Raman spectroscopies. The magnetic susceptibilities of the complexes were measured to confirm the hybridization patterns and the geometries. Single-crystal X-ray analyses of Ni(L)(2) and [Co(L)(2)](2) complexes were also carried out to prove the molecular topologies.
