The reaction of 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4- disulfide (Lawesson's Reagent) with two different Grignard reagents gave the corresponding dithiophos-phinic acids (DTPA), CH3OC6H 4-(R)P(S)SH; [R = iso-butyl (HL1) and sec-butyl (HL 2)]. HL1 and HL2 were treated with dry ammonia to convert them to the ammonium salts, NH4L1 and NH 4L2. Ni(II) and Co(II) complexes of L1 and L2 - [Ni(L1)2], [Ni(L2) 2]; [Co(L1)2]2 and [Co(L 2)2]2-were obtained by the reaction of NH 4L1 and NH4L2 with NiCl 2.6H2O and CoCl2.6H2O, respectively, in ethanol. Square-planar nickel complexes [Ni(L1)2] and [Ni(L2)2] were further reacted with pyridine (Py) to obtain the octahedral complexes, [Ni(Py)2(L1)2] and [Ni(Py)2(L2)2]. The compounds were characterized by elemental analysis, FTIR, APCI/ESI-MS and 1H, 13C, and 31P NMR spectroscopies. The novel nickel(II) complex [Ni(L2)2] was characterized by X-ray crystallography.
