Synthesies and crystal structure of Co[(C_2H_5O)_2PS_2]_2(C_(12)H_8N_2)

为研究二烃基二硫代磷酸酯合过渡金属配合物与氮碱加合物的性能,合成了二乙基二硫代磷酸酯合钴(Ⅲ)配合物,利用其与邻菲咯啉的加合反应,得到了Co[(C_2H_5O)_2PS_2]_2(C_(12)H_8N_2)配合物并测定了它的晶体结构.Co(Ⅱ)与2个二硫代磷酸酯的4个硫原子和邻菲咯啉分子中的2个氮原子形成六配位的八面体结构.二硫代磷酸酯分子中的磷原子与2个硫原子2个氧原子形成四面体的结构.

To study the properties of the adduct formation of dialkyldithiophosphate coordination compound of intergrade metal with nitrogen base, Co[(C_2H_5O)_2PS_2] were synthesized. Co[(C_2H_5O)_2PS_2]_2(C_~12 H_8N_2) were obtained by adductive reaction between Co[(C_2H_5O)_2PS_2]_3 and phenanthroline. The crystal and molecule structures of title complex were analyzed. The cobalt atom in the title complex has a octahedral geometry with four Co-S bonds and two Co-N bonds. The central atom P is tetrahedrally surrounded by two sulphur atoms and two oxygen atoms in the diethyldithiophosphate ligand.
