Dynamic disorder in a pentacoordinate silicon complex with 2,2'-diazenediyldiphenol.
The crystal structure of (2,2'-diazenediyldiphenolato-kappa(3)O,N,O')dimethylsilicon, C(14)H(14)N(2)O(2)Si, determined at four temperatures, reveals a dynamic disorder as a result of a flipping of the orientation of the C-N=N-C unit. The population of the two conformers in the single crystal depends on the temperature and cooling rate. It is possible to minimize the disorder by cooling the crystal slowly.
