Hydrothermal synthesis and crystal structure of a novel 2-D coordination polymer [Mn2(pdc)2(H2O)3]nz2nH2O (pdc ¼ pyridine-2,3-dicarboxylate)

A novel 2-D coordination polymer [Mn2(pdc)2(H2O)3]nz2nH2O (pdc ¼ 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 ¼ 23:900ð5Þ A ° , b ¼ 8:581ð2Þ A ° , c ¼ 19:833ð4Þ A° , b ¼ 106:51ð3Þ8; V ¼ 3899:8ð15Þ A° 3, Z ¼ 8 and R ¼ 0:0425: The title compound consists of two kinds of MnII 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. q 2004 Elsevier B.V.
