Syntheses and structural elucidation of the some novel thio-phosphorus group complexes

In this study, some dithiophosphinic acids were synthesised (CH3O-C6H4-(RO)P(S)S-NH4+; R = -C5H11 ve –(CH2)3-C6H5) as a ammonium salts, and some novel complexes were synthesised by the reaction of metal cations with ammonium salts ([M(CH3O-C6H4-(RO)P(S)S)2]n, n= 1, M= Ni2+; n= 2, Cd2+, Hg2+, R= -C5H11, –(CH2)3-C6H5). In the first step the dithiophosphinic acids were obtained by means of reaction of between Lawesson reagent (2,4-bis(4-methoxyphenyl)-1,2,3,4-dithiaphosphetane-2,4-disulfide) and some alcohols. Then these acids were converted their ammonium salts. Some novel octahedral nickel complexes were also synthesized by the reaction of some novel square planar which is obtained in this work with pyridine ({Ni(CH3-O-C6H4-(RO)P(S)S)2Py2} R= -C5H11, -(CH2)3-C6H5). The complexes and ligands were characterized by elemental analysis, melting point and 1H-, 13C-, 31P-NMR, MS, FTIR. The magnetic susceptibilities of the complexes which are {Ni(CH3-O-C6H4-(RO)P(S)S)2Py2} (R= -C5H11, –(CH2)3-C6H5) were measured to confirm the hybridization patterns and the geometries. The novel some complexes which are AE2-NiPy, AE2-Ni and AE2-Cd were elucidated by X-ray crystallography.
