Tetranuclear pyrophosphate-bridged Cu(II) complex with 2,2?-dipyridylamine: Crystal structure, spectroscopy and magnetism
Use of pyrophosphate, 2,2?-dipyridylamine (hdpa) with Cu(NO3)2 ¡¤ 3H2O has enabled to synthesize a novel tetranuclear copper(II) complex, [Cu4(hdpa)4(mu-P2O7)2] ¡¤ 11H2O 1, which was characterized by single crystal X-ray diffraction, IR, ESR spectrum, and variable-temperature magnetic susceptibilities (4.2-300 K). Extensive pi-pi stackings and H-bonding water clusters resulting from 11 free water molecules join Cu4 units to make a 3D network. According to the molecular structure, the experimental data were fitted to the expressions derived from the Hamiltonian H = – 2 J12 over(S, ^)1 over(S, ^)2 – 2 J13 (over(S, ^)1 over(S, ^)3 + over(S, ^)2 over(S, ^)4) – 2 J14 (over(S, ^)1 over(S, ^)4 + over(S, ^)2 over(S, ^)4) showing dominant antiferromagnetic behaviors.
