Addition of pnictogen atoms to chromium(<scp>ii</scp>): synthesis, structure and magnetic properties of a chromium(<scp>iv</scp>) phosphide and a chromium(<scp>iii</scp>) arsenide

Abstract

Chromium(<sc>ii</sc>) chloride reacts with LiCp* (Cp* = C₅Me₅) and LiE (SiMe₃)₂ (E = P or As) to give the chromium(<sc>iv</sc>) phosphide [(η⁵-Cp*Cr)(μ₃-P)]₄ (<bold>1</bold>) or the chromium(<sc>iii</sc>) arsenide [(η⁵-Cp*Cr)₃(μ₃-As)₂] (<bold>2</bold>), respectively.
