Supramolecular assemblies of new 2-D complexes: Syntheses, crystal structures, spectroscopic and magnetic properties of {[MnAu2(CN)4(NITpPy)2(H2O)2]}n and {[Co(N(CN)2)2(NITpPy)2(H2O)2]}n

Two new complexes containing 3d metal, pyridyl-nitronylnitroxides, and anionic bridging ligands, which show the fascinating structures with magnetic properties, have been prepared. The structure of the complexes illustrates that aurophilicity or hydrogen bonding interactions increase dimensionality, generating a 2-D system. The magnetic properties for 1 and 2 have been investigated.
