A One-dimensional Manganese(H) Coordination Polymer with 4′-Hydroxybiphenyl-4-carboxylate as the Single Ligand: Synthesis, Crystal Structure and Luminescence

A new 1D coordination polymer, {[Mn-2(4',4-hbc)(4)(4',4-Hhbc)(2)(H2O)center dot H2O}(n) (4',4-Hhbc = 4'-hydroxyl-biphenyl-4-carboxylic acid), has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group C2Ic with a = 52.421(10), b = 7.5388(15), c = 16.478(3) angstrom, beta= 106.12(3)degrees, V = 6256(2) angstrom(3), Z = 4, C78H62Mn2O21, M-r = 1445.16, D-c = 1.534 g/cm(3), mu(MoK alpha) = 0.490 mm(-1), F(000) = 2992, R = 0.0764 and wR = 0.2006 for 2984 observed reflections with I > 2(7(4 X-ray diffraction analyses reveal that the title compound is a one-dimensional infinite chain, in which the Mn-II atom adopts a distorted octahedral geometry coordinated by four 4',4-hbc ligands, one 4',4-Hhbc ligand and one water molecule. Furthermore, the luminescent property of title compound was investigated.
