An eleven-vertex metallaborane with tetracapped pentagonal bipyramidal geometry†
Abstract
A metallaborane of novel structure, [(Cp*Mo)2B3H3Se2{Fe(CO)2}2{Fe(CO)3}2] (2; Cp* = η5-C5Me5), with tetracapped pentagonal bipyramidal geometry, isolated from the reaction of [(Cp*Mo)2B4H4Se2], 1 with [Fe2(CO)9]; the title compound exhibit an 11-vertex closo-cage geometry, having eight skeletal electron pairs (sep) and 98 valence electrons, appropriate for its geometric structure.
