Macropolyhedral boron-containing cluster chemistry. Nineteen-vertex [S2B17H17(SMe2)]. An unusual apical boron atom of cluster connectivity six that introduces a new polyhedral borane building block
Abstract
Mild thermolysis of [SB8H10(SMe2)] results in the formation of a small amount of macropolyhedral [S2B17H17(SMe2)] of which the stucture is based on the fusion, with two boron atoms in common, of a conventional nido-type eleven-vertex {SB10H9} subcluster with an unprecedented arachno-type ten-vertex {SB9H8(SMe2)} subcluster that exhibits an apical boron atom of cluster connectivity six.
