摘要：
A new refinement of the isomeric pair of compounds Me(3)Ge-SnPh(3) (I) and Ph(3)Ge-SnMe(3) (II), using full sets of Friedel opposite reflections, is reported. The Ge-Sn bond length (I: 2.602(1) and II: 2.611(1) Angstrom) difference was found to be significantly smaller (Delta = 0.009 Angstrom) than reported previously (0.053 Angstrom). A solid solution of the isostructural pair I and II was obtained by recrystalizing equimolar quantities of the isomer compounds and the disordered crystal structure was elucidated. The solid solution contains I:II in 0.375:0.625 ratio.
