group P21/c with these cell dimensions: a = 11.046(2)Å, b = 18.168(3)Å, c = 12.678(3)Å, β = 110.24(2)° and V = 2387(2)Å3 for1 and a = 11.055(1)Å, b = 18.199(3)Å, c = 12.693(2)Å, β = 110.16(1)°, V = 2392(1)Å3 for2. The molecules of1 and2 are isostructural. Metal atoms reside on inversion centers relating the two halves of the molecules. The complexes are six-coordinate with two four-membered chelate
研究了Os 2(O 2 CCH 3)4 Cl 2与vdpp [vdpp = 1,1-双(二苯基膦基)乙烯]之间的反应。当反应物,在氯化锂的存在下,在甲苯中加热OSCL 2(vdpp)2,1,被形成了。在相似的反应的Ru 2(O 2 CCH 3)4 Cl可vdpp得到的RuCl 2(vdpp)2,2。使用X射线晶体学阐明了1和2的分子结构。1和1的单晶从二氯甲烷己烷中生长的2在空间群P 2 1 / c中具有以下晶胞尺寸结晶:a = 11.046(2)Å,b = 18.168(3)Å,c = 12.678(3)Å,β= 110.24(2)°和V = 2387(2)埃3为1和一个= 11.055(1)埃,b = 18.199(3)埃,c ^ = 12.693(2)埃,β= 110.16(1)°,V = 2392(1)埃3为2。1和2的分子是同构的。金属原子位于与分子的两个半部分相关的反转中心上。
