摘要：

A new tp-bridged complex [Ni(pyrazole)(4)(tp)](n), (1; tp = terephthalate) coordinated with a nonchelating pyrazole ligand has been synthesized and characterized using X-ray structure determination and magnetic studies. The crystal structure reveals that the capping ligand functions as a source of hydrogen bonding and intermolecular contacts, such as pi-pi and CH-pi interactions, that result in a three-dimensional supramolecular assembly. Weak antiferromagnetic couplings are transmitted between Ni-II centers through the tp linkage. ((c) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005).
