Its crystal structure was determined by single crystal X-ray diffraction techniques. Crystal data: monoclinic, space group P21/c, a=0.712 21(8) nm, b=1.170 93(14) nm, c=1.783 7(2) nm, β=111.828(2)°, and V=1.380 8(3) nm3, Dc=1.769 Mg·m-3, Z=2, F(000)=744, R1=0.025 4, wR2=0.069 5, Gof=1.077, Δρ=328^-455 e·nm-3. The complex is packed by one centrosymmetry binuclear copper(Ⅱ) unit, oxalate dianion and NO3- anion. In the molecule structure of the title complex, two Cu(Ⅱ) ions are bridged by oxalate dianion and each Cu(Ⅱ) ions coordinates with two nitrogen atoms from 1,10-phenanthroline ligand and one oxygen atom from water to form a five-coordinate distorted square-pyramidal configuration. The hydrogen bonds are observed between coordinated water molecules and NO3- anions. The analysis of the crystal structure indicates that the complex has a two-dimensional stacking network structure, which is formed by intramolecular hydrogen bonds, intermolecular hydrogen bonds and stacking effect of aromatic ring.

Further, a new coordination polymer, {[FeⅡFeⅢ(ox)3]·1.5H2O}∞(2), was synthesized and characterized, where ox2-=oxalate. The results of the IR and Mssbauer spectra of 2 revealed that the coordination polymer exists 2 D layer structure in the solid state, and anions layer was formed by [FeⅡFeⅢ(ox)3]-unit. The magnetic properties of 2 have been measured and the results indicate that there is magnetic ordering in the low temperature, which may arise from intermolecular ferromagnetic interactions or spin canted effects.展开更多
