Redetermination of the trigonal prismatic complex tris(cis-1,2-diphenylethylene-1,2-dithiolato)rhenium

Acta Cryst. (2006). C62, m464–m466 [doi.org/10.1107/S0108270106033336]

The first structurally characterized example of trigonal prismatic coordination reported forty years ago, Re(S₂C₂Ph₂)₃, was redetermined from the same sample using modern CCD instrumentation. The results confirm the original determination, albeit with better agreements among bond distances and angles and without using a group refinement for the phenyl rings. A survey of related MS₆ molecules reported over the years is included that assesses the degree of trigonal prismatic coordination using a designated dihedral angle for comparison.
