X-ray structural study of 3:1 solvate of 1-chlorosilatrane with MeCN

The single-crystal X-ray study of ClSi(OCH₂CH₂)₃N showed the formation of a cluster of three silatrane molecules with one acetonitrile molecule featuring hypercoordinated Si atoms in a trigonal-bipyramidal coordination environment with O atom in the equatorial plane. A number of solid-phase structural parameters and the conformation of the fivemembered rings of 1-chlorosilatrane were thus clarified.
