[Me2Sn(CH2)3SnMe21.5Co(CN)6], 1, and [Me2Sn(CH2)3SnMe22Mo(CN)8], 2, have been prepared and compared with their notional ‘parent’ systems [(R3Sn)3Co(CN)6] (R = Me, Et, nBu) and solvent-free [(Me3Sn)4M(CN)8] (M = Mo, W) respectively. Results of extensive spectroscopic (i.e. IR/Raman as well as multinuclear CP MAS NMR) studies and of X-ray powder diffractometry suggest that the crystal structures of 1 and 2 involve
制备了两种新化合物[Me 2 Sn(CH 2)3 SnMe 2 1.5 Co(CN)6 ],1和[Me 2 Sn(CH 2)3 SnMe 2 2 Mo(CN)8 ],2。并与其名义上的“母体”系统[(R 3 Sn)3 Co(CN)6 ](R = Me,Et,n Bu)和无溶剂的[(Me 3 Sn)4 M(CN)8](M = Mo,W)。广泛的光谱学(即IR / Raman以及多核CP MAS NMR)研究和X射线粉末衍射分析的结果表明,1和2的晶体结构涉及三维网络,与它们的“母体”系统明显不同。两个CNSnMe 2 CH 2配体片段可能通过第三个CH 2基团成对规则地连接,甚至似乎“改善”了各个M(CN)k结构单元的局部对称性(k = 6或8),并简化了相应的M(CN)k结构单元。不对称单位。
