Derivatives of Osmium(IV): Crystal Structures of trans-[OsCl4(HNPEt3)2] and (H2NPPh3)2[OsCl6]·2CH3CN trans-[OsCl4(HNPEt3)2] (1) was prepared by reaction of osmium pentachloride with the silylated phosphoraneimine Me3SiNPEt3 in dichloromethane solution forming yellow moisture sensitive single crystals. The hexachloroosmate(IV) (H2NPPh3)2[OsCl6]·2CH3CN (2) was obtained as yellow single crystals from osmium pentachloride
锇 (IV) 的磷胺衍生物:反式-[OsCl4(HNPEt3)2] 和 (H2NPPh3)2[OsCl6]·2CH3CN 的晶体结构反式-[OsCl4(HNPEt3)2] (1) 是通过五氯化锇与甲硅烷基化磷胺 Me3SiNPEt3 在二氯甲烷溶液中形成黄色湿敏单晶。六氯锇酸盐(IV) (H2NPPh3)2[OsCl6]·2CH3CN (2) 从五氯化锇和N-氯三苯基膦亚胺ClNPPh3 在乙腈溶液中得到黄色单晶。图1和2通过IR光谱和单晶X射线结构测定表征。1:空间群 P21/c,Z = 2,193 K 时的晶格尺寸:a = 830.9(1),b = 1031.1(1),c = 1307.7(1) pm,β = 106.15(1)°,R1 = 0.0248。1 形成中心对称分子,平均距离 Os-N 为 202.9(4) pm,Os-Cl 平均为 234.7 pm。2:空间群,Z = 2,193
