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 π–π and CH–π interactions, that result in a three‐dimensional supramolecular assembly. Weak antiferromagnetic couplings are transmitted between Ni II centers through the tp linkage. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
