【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. 438(3)A , b = 14. 885(6) A , c=6. 366(3) A ,a=99. 25(4)°, β=93. 46(4)°, γ=92. 01(3)°,V=787A, Dc= 1. 70 g.cm-3, Z=l, F(0 0 0) = 426e. Space group is P1. R=0. 085.更多还原
