Abstract: Reaction of Ni[(C6H11O)2PS2]2 with pyridine was studied spectrophotometrically and the equilibrium constants was found to be k=15.4±1.40(mol/L)-1 and β2=(1.43±0.41)× 103 (mol/L)-2.The crystal structure of Ni[(C6H11O)2PS2]2.2Py was measured by X-ray diffraction method.The crystal belongs to a monoclinic system with the parameters of unit cell a=8.938(3)Å,b=19.885(6)Å, c=6.366(3)Å,a=99.25(4)°,β=93.96(4)°, γ=92.01(3)°,V=787Å3, Dc= 1.70 g·cm-3, Z= 1, F(000)=426e.Space group is P1 R=0.085.

Key words: Dialkyldithiophosphate, Nickel(Ⅱ) coordination compounds, Crystal structure, Adductive equilibrium constant
