A novel metal–organic ternary topology constructed from triangular, square and tetrahedral molecular building blocks.

A novel metal–organic network [Cu4(5-NH2-1,3-bdc)4(pyridine)2(H2O)2]n, displaying an unprecedented topology has been constructed utilizing the different coordinating functional groups of 5-NH2-1,3-bdc to generate a ternary network based upon vertex-linked triangular, square and tetrahedral molecular building blocks (MBBs).
