A novel tetranuclear copper(II) complex with three different types of azide, exhibiting weak antiferromagnetic exchange
Abstract
The antiferromagnetically coupled, tetranuclear copper(II) complex [Cu4(pap)2(µ-1,1-N3)2(µ-1,3-N3)2(µ-MeOH)2(N3)4]1 contains a unique structural arrangement with two µ-1, 1-azide intramolecular bridges, and two µ-1,3-azide intermolecular bridges linking pairs of copper(II) centres, in addition to four terminal azide groups.
