Two new ion-pair complexes [Co(BBP)2]2[Ni(mnt)2]Cl2·4DMF·2H2O(1, BBP =2,6-bis(benzimidazol-2'-yl) pyridine, mnt = maleonitriledithiolate) and [(Py)2CH2][Co(mnt)2]2·4DMF(2) have been synthesized and characterized by elemental analyses, IR spectroscopy,thermogravimetric analyses and single-crystal X-ray diffraction. X-ray diffraction studies show that complex 1 crystallizes in monoclinic, space group P21/c. The crystal of 2 belongs to a triclinic system with space group P1. Due to the hydrogen bonding interactions, anions and cations formed the mixed packing in complex 1 while the anions and cations formed segregated columns in 2. In addition, thermogravimetric analyses of the two complexes are also investigated. 相似文献

A novel coordination polymer [Ba2(AQTC)(H2O)3]n(1, H4 AQTC = anthraquinone-1,4,5,8-tetracarboxylic acid) has been prepared under hydrothermal conditions and characterized by single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy and thermogravimetric analysis. Two quinone oxygen atoms and all carboxylate oxygen atoms of AQTC4- are involved in coordination. Two equivalent barium ions are mainly linked by carboxylate oxygen atoms into a dimer. Neighbouring dimers are further connected by the AQTC4- ligand through carboxylate oxygen atom, leading to a 1-D chain structure. Every two adjacent chains are mainly further connected by face carboxylate oxygen atoms and water molecule, generating a two-dimensional layer structure. Such 2-D layer structures are connected with O(6) and O(6C) atoms from water molecules to form a 3-D structure. In addition, luminescent properties of 1 are also investigated. 相似文献
