and 1H NMR spectra, and the crystal structure of 3 was determined by X-ray diffraction. Crystals of 3 are monoclinic, with space group P21/n and Z = 4 with the unit cell dimensions a 9.7936(17), b 14.844(35), c 23.530(64) Å, β 91.817 (18)°, and V 3419.09(1.36) Å3. The structure is refined to final discrepancy factors of R = 0.055, and Rw = 0.064. The molecular structure of 3 is that ligating atoms
PtPCy 3(C 2 H 4)2(Cy =环己基)的烃溶液与8-喹啉甲醛(1当量)快速反应,生成三环己基膦喹啉羧基氢化铂(1)和CH 2 CH 2(2当量)。化合物1与CCl 4在烃中反应生成PtPCy 3(NC 9 H 6 CO)Cl(2)和CHCl 3。化合物PtPCy 3(C 2 H 4)2也与Ph 2 P(C6 ħ 4 - ö -CHO)和pH 2如(C 6 H ^ 4 - ö -CHO),得到PCY 3乍得人道主义保护2 P(C 6 H ^ 4 - Ô -CO)(H)(3)和PCY 3乍得人道主义保护2如(C 6 H ^ 4 - Ô -CO)(H)(4),分别。通过红外光谱和1 H NMR光谱对化合物1、2、3和4进行表征,并确定3的晶体结构。通过X射线衍射确定。3的晶体是单斜晶体,其空间群P 2 1 / n和Z = 4,其晶胞尺寸为9.7936(17),b 14.844(35),c
