Novel binuclear copper(I) complexes with unusual azide and thiocyanate bridges. Crystal structures of [Cu2(µ-Ph2Ppypz)2(µ-1,1-N3)][ClO4]·Et2O and [Cu2(µ-Ph2Ppypz)2(µ-1,1-SCN)][ClO4] [Ph2Ppypz = 2-(diphenylphosphino)-6-(pyrazol-1-yl)pyridine]

Abstract

The first binuclear copper(I) complex with a µ-1,1-N₃ bridge, [Cu₂(µ-Ph₂Ppypz)₂(µ-1,1-N₃)][ClO₄]·Et₂O and [Cu₂(µ-Ph₂Ppypz)₂(µ-1,1-SCN)] [ClO₄] [Ph₂Ppypz = 2-(diphenylphosphino)-6-(pyrazol-1-yl)pyridine], which exhibits an unusual thiocyanate (µ-1,1-SCN) bridge, have been synthesised and characterised.
