摘要
在金属配合物的结构及其功能研究中,利用分子间非共价键的弱相互作用(静电作用、氢键、范德华力或π-π堆积等)构建超分子晶体体系引起人们极大的研究兴趣^[1,2]。分子间氢键的相互作用,可使配合物单分子之间相互连结,从而得到一维、二维或三维网络结构的超分子化合物。
The title compound [Mn(phendione)(PDC)(H2O)2]·2H2O(H2PDC=pyridine-2,6-dicarboxylic acid) has been prepared in aqueous solution and characterized by single X-ray diffraction structure determination, elemental analysis, IR spectroscopy, and thermal analyses. The compound crystallizes in Monoclinic system, space group C2/c, a=l.017 51(11) nm, b=1.483 25(11) nm, c=1.461 21(13) nm,/3=109.86(10)°, V=2.074 1(3) nm^3, Z=4, F(000) =1028,μ=0.701 mm^-1, Dc=1.609 g·cm^-3, R1=0.0289, wR2=0.0788 [I〉2σ(I)]. Crystal structure reveals that complex consists of one-dimensional chain framework bridged by hydrogen bonds that formed by uncoordinated water and oxygen atom of earboxyl group in PDC^2-. Furthermore, the complexes form a three-dimensional super-molecular structure through hydrogen bonds. CCDC: 648570.
