摘要
A novel two-dimensional Mn（II） coordination polymer, [Mn3（L）R（cis-chdc）fftrans- chdc）]n （L = 2-amino-4-（1H-imidazo[4,5-J][1,10]phenanthrolin-2-yl）phenol and chdc = 1,4-cyclo- hexanedicarboxylate）, has been hydrothermally synthesized and characterized by elemental analysis, IR, TG PL and single-crystal X-ray diffraction. Crystallographic data for this compound： monoclinic space group P2/n with a = 11.0058（13）, b = 9.0179（11）, c = 28.431（3） A, β = 92.850（2）°, V = 2818.3（6） A3, Z = 2, C62Hs6Mn3N10O14, Mr = 1329.99, Dc = 1.567 g/cm3, F（000） = 1370, p（MoKa） = 0.742 mm-1, R = 0.0553 and wR = 0.1421. The chdc carboxylates bridge the Mn（II） atoms to form a trinuclear Mn（lI） cluster. The cis-chdc ligands are held together by the trinuclear Mn（II） clusters to result in a chain structure. Further, the trans-chdc ligands link adjacent chains to furnish a two-dimensional network. The π-π interactions between neighboring layers link the adjacent layers into a three-dimensional supramolecular architecture. Moreover, the N-H...O and O-H...O hydrogen bonds further stabilize the 3D supramolecular architecture.
