Two new coordination polymers, [M(phen)(e,a-cis-1,4-chdc)(H_2O)]_n (M=Mn (1); M=Cu (2); chdc=cyclohexanedicarboxylic acid; phen=1,10-phenanthroline), were prepared under hydrothermal conditions and characterized by IR spectra and single crystal X-ray diffraction analysis. X-ray crystal structural analyses reveal that polymer 1 and 2 are isomorphic and belong to the monoclinic system. C_ 20H_ 20MnN_2O_5, P_2(1)/c, a=1.023?5(2) nm, b=0.891?34(19) nm, c=2.046?6(4) mm, β=99.820(3)°, Z=4 for 1; and C_ 20H_ 20CuN_2O_5, P2(1)/c, a=1.000?2(3) nm, b=0.894?9(2) nm, c= 2.027?0(5) nm, β=99.694(3)°, Z=4 for 2. In the structures of 1 and 2, the 1,4-chdc ligand only possesses e,a-cis conformation although there are both cis- and trans-conformations in the raw material.
Two new coordination polymers [M (phen) (e, a-cis-1,4-chdc) (H_2O)] n (M = Mn 1,10-phenanthroline), were prepared under hydrothermal conditions and characterized by IR spectra and single crystal X-ray diffraction analysis. X-ray crystal structural analyzes reveal that polymer 1 and 2 are isomorphic and belong to the monoclinic system. C_20H_20MnN_2O_5 (2) nm, b = 0.891? 34 (19) nm, c = 2.046? 6 (4) mm, β = 99.820 (3) nm, b = 0.894? 9 (2) nm, c = 2.027? 0 (5) nm and? = 99.694 (3) °, Z = 4 for 2. In the structures of 1 and 2, the 1,4-chdc ligand only possesses e, a-cis conformation there there are both cis- and trans-conformations in the raw material.
