Abstract

New photocatalytically active isostructural two-dimensional mixed metal-pyridine dicarboxylates, $[M(H_2O)_3Co\{C_5N_1H_3 (COO)_2 \}_3])\infty]$, M = Gd (1), Dy (2) and Y (3) have been prepared under hydrothermal conditions. The structure consists of a network of $MO_6(H_2O)_3$, $CoO_3N_3$ polyhedral units connected by the pyridine dicarboxylates forming two-dimensional layers, which are arranged in an AAAA... fashion. The photocatalytic studies on 1 – 3 indicate that they are active catalysts for the degradation of simple organic dyes, such as Remazol brilliant blue R (RBBR) and Orange G (OG) in the presence of UV light. The compounds have also been characterized by powder XRD, IR, TGA, UV-Vis and magnetic studies.
