چکیده انگلیسی

Reaction of anhydrous copper(II) chloride with N,N,N′,N′-tetraisopropylpyridine-2,6-dicarboxamide (L) leads to the synthesis of [Cu2Cl4L2]·2CH3CN, 1. The ligand coordinates to each CuII ion in a bidentate fashion through pyridine nitrogen and only one of the carbonyl oxygen atoms of the amide group rather than using tridentate coordination mode O–N–O. The structure can be described as a dichloro bridged centrosymmetric dimer where the two copper centers are pentacoordinated in a square pyramidal fashion. The two pyramids are arranged sharing a basal edge with their apical positions oriented opposite to each other. The crystal packing investigations show a 2D sheet in the lattice held together by dimeric acetonitrile entities. Complex 1 shows weak antiferromagnetic coupled Cu2+ ions.
