Two new coordination polymers, [M(phen)(e, a-cis-1, 4-chdc) (H2O)]n (M = Mn^(1); M = Cu^(2); chdc = cyclohexanedicarboxylic acid; phen = 1, 10-phenanthroline), were prepared under hydrothermal conditions a...Two new coordination polymers, [M(phen)(e, a-cis-1, 4-chdc) (H2O)]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. C20H20MnN2O5, P2 (1) / c, a=1.0235(2) nm, b=0.89134(19) nm, c=2.0466(4) mm,β=99.820(3), Z=4 for 1; and C20H20CuN2O5, P2(1)/c, a=1.0002(3)nm, b=0.8949(2)nm, c=2.0270(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.展开更多

Coordination reaction between H 2HAPP and metal ion Zn(Ⅱ) in CH 3OH CH 2Cl 2[ V (CH 3OH)∶ V (CH 2Cl 2)=1∶1] solvent was studied by UV Vis spectroscopic method, which indicated 1∶1 complexing between H 2HAPP and Zn(II) ion occurred easily in such a homogeneous system at room temperature. And the formation of ZnHAPP complex was further confirmed by FAB MS and 1H NMR spectra.展开更多
