“…25, No.4, 2002 (5)244 pm (Si) There is one example Ge(Ph) 3 (OH) [93] which contains eight crystallographically independent molecules,,mostly differing by degree of distortion (Ge-L and L-Ge-L). Three such molecules are found in Ge(Me) 2 (rf-cbc) [75} In several other derivatives [44,47,48,55,58,65,75,89,95,98,99,102,108,116,117,119,124,134,151] two such molecules are present. All of these belong to the class of distortion isomerism [11}…”
