CoAu2(CN)4(NITpPy)2(H2O)2]n: a new 2-D interdigitating complex containing dicyanoaurate(I) anion, a radical, and cobalt(II) ion incorporating gold...gold and hydrogen bonding interactions

A novel complex, CoAu2(CN)4(NITpPy)2(H2O)2]]n, 1, containing the cobalt(II) ion, dicyanoaurate(I) anion, and nitronyl nitroxide radical building blocks, has been prepared and structurally characterized by single-crystal X-ray analysis. The structure of complex 1 illustrates that aurophilicity and hydrogen bonding interactions increase dimensionality, generating a 2-D interdigitating system. The spectroscopic and magnetic properties have been investigated.
