The so far unknown lead tricyanomethanide, Pb[C(CN)3]2, was obtained from a saturated aqueous solution of PbCl2 and solid AgC(CN)3. Its IR spectrum and thermal behaviour are described. The crystal structure was determined by single-crystal X-ray diffraction (trigonal, P31m, Z = 3, a = 1414.4(5), c = 409.02(6) pm, R1 = 0.0249, wR2 = 0.0527). Two crystallographically independent ninefold coordinated
迄今为止未知的三氰基甲烷化铅 Pb[C(CN)3]2,是从 PbCl2 和固体 AgC(CN)3 的饱和水溶液中获得的。描述了其红外光谱和热行为。晶体结构由单晶X射线衍射确定(三角,P31m,Z = 3,a = 1414.4(5),c = 409.02(6)pm,R1 = 0.0249,wR2 = 0.0527)。两个晶体学独立的九重配位铅原子通过平面三氰基甲烷离子以两种不同的桥接配位模式连接。Pb-N 距离范围在 254 到 293 pm 之间。
