Hydrothermal synthesis and crystal structure of a novel 2-D coordination polymer [Mn 2(pdc) 2(H 2O) 3] n[rad]2 nH 2O (pdc=pyridine-2,3-dicarboxylate)

Abstract

A novel 2-D coordination polymer [Mn 2(pdc) 2(H 2O) 3] n 2 nH 2O (pdc=pyridine-2,3-dicarboxylate) 1 has been hydrothermally synthesized and characterized by the elemental analyses, IR spectrum, TG analysis along with the single crystal X-ray diffraction. Colorless platelet crystals of compound 1 crystallize in the monoclinic system, space group C2/ c, a=23.900(5) Å, b=8.581(2) Å, c=19.833(4) Å, β=106.51(3)°, V=3899.8(15) Å 3, Z=8 and R=0.0425. The title compound consists of two kinds of Mn II center with different coordination environments by pdc and water ligands, to form a 2-D sheet, and then constructs a 3-D network by interlayer hydrogen bonds.
