- Abstract
- Two new trinuclear complexes 1 and 2 that are composed of the three-directional ligand 2,4,6-tris(di-2-pyridylamino)-1,3,5-triazine (dipyatriz) and copper(II) chloride as well as a 1D polymeric zigzag system 3 assembled from trimetallic type 2 building blocks have been prepared and structurally characterized. While the triazine-N are not involved in metal coordination, each ligand bidentately binds to three copper ions via its three pairs of pyridine-N donors, and five-coordination of the copper is completed by chloride or dmso solvent molecules. Variable-temperature magnetic studies reveal weak antiferromagnetic coupling. Magnetic properties of the trinuclear entities and of the bis(mu-chloro) bridged pseudo-dimeric copper(II) subunits in 3 can be rationalized on the basis of the structural findings.
