M. Westerhausen et al., Synthesis and structure of solvent-free hexameric magnesium tri(tert-butyl)silylphosphandiide, INORG CHEM, 38(3), 1999, pp. 598
Hexameric magnesium tri(terl-butyl)silylphosphandiide crystallizes with a h
exagonal Mg6P6 prism and is a rare example of a solvent-free phosphandiide
of a hard main group metal. The magnesium atoms show a coordination number
of 3 in a trigonal pyramidal surrounding.
