Hydrothermal Synthesis and Crystal Structure of Three-dimensional Supramolecular Zinc, Manganese Coordination Polymers Zhi-Tao Wang • Valentin Valtchev • Qian-Rong Fang • Xiu-Mei Li • Ya-Ru Pan Two new complexes [Zn 2 (pzdc)(L) 2 (H 2 O)] 2n •2nH 2 O (1) and [Mn(µ 2-O)(H 2 O) 2-(HL)] 2n •2nNIPH (2) (H 2 pzdc = pyrazine-2,3-dicarboxylic acid, HL = 3-(2-Pyridyl) pyrazole, H 2 NIPH = 5-nitroisophthalic acid) have been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, UV spectrum, TG, fluorescence spectrum and single-crystal X-ray diffraction. Complex 1 shows two-dimensional (2D) network, which was stabilized by O-H•••O, C-H•••O hydrogen bonding and π-π interactions and extended into 3D supramolecular architecture. Complex 2 is zero-dimensional structure, which was further extended into 3D supramolecular framework through N-H•••O, O-H•••O, C-H•••O hydrogen bonds and π-π interactions.
