Metal-organic frameworks built from achiral 3-(5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)benzoic acid: syntheses and structures of metal(II) complexes.

Using a novel flexible achiral ligand, 3-(5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)benzoic acid (HL), four metal(II)-complexes formulated as ZnL2·2H2O (1), CdL2(H2O)2·8H2O (2) and ML2(H2O)·H2O (M = Co 3 and Ni 4) have been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. Complexes 1, 3 and 4 all feature a uninodal 2D layer with a 4(4)-sql topology, and two such (4,4) nets interpenetrate in a parallel manner. Complex 2 exhibits a similar 4(4)-sql topology, but no interpenetration is observed in complex 2.
