Two transition metal coordination polymers constructed from 3-aminobenzoate and 4,4′-bipyridine

Abstract

Two new transition metal coordination polymers, [Zn(abz)(bipy)](ClO₄) (1) and [Mn(bipy)₅(H₂O)₆](ClO₄)₂· 2(abz) · 2(H₂O) (2) (bipy = 4,4′-bipyridine, abz = 3-aminobenzoate), were prepared and characterized by elemental analysis, FTIR spectroscopy, and single-crystal X-ray diffraction. Complex 1 is a 2-D-layered network with a (4,4) net built up by bipy and 3-aminobenzoate ligands connecting two zinc nodes. Complex 2 is a 3-D supramolecular grid network constructed from close stacking bipy ligands of H-type cation units with large cavities hosting 3-aminobenzoate, perchlorate ions, and water. Solid state photoluminescence for 1 was also investigated.
