Preparation of stable copper(<scp>I</scp>) derivatives of the octahydropentaborate(1–) and nonahydrohexaborate(1–) ions

Abstract

Compounds (Ph3P)2CuB5H8 and (Ph3P)2CuB6H9, the first air-stable derivatives of pentaborane(9) and hexaborane(10), have been prepared and studied for possible insertion of the metal into the bridge position.
