Two novel clusters [Mn~Ⅲ_3(μ_3-O)(phendox)3]X·13H_2O(X = Cl(1), Br(2]) have been obtained from the solvothermal reactions of 1,10-phenanthroline-2,9-dicarbaldehyde dioxime(H_2phendox) with MnCl_2·4H_2O or anhydrous MnBr_2, and their structures were characterized by elemental analysis, FT-IR, XRD, TGA, MS and single-crystal X-ray diffraction. It crystallizes in trigonal, space group P3_1/c. X-ray analysis reveals that the neighbouring [Mn_3(μ_3-O)(phendox)_3]+ cores are linked by C–H···Cl hydrogen bonds and form an infinite supramolecular chain along the c-axis. Neighbouring chains are packed with each other by off-set p-p interactions of the aromatic rings on phenox2-. A 3D supramolecular architecture in a honeycomb topology is formed with 1D hexagonal channel in the dimensions of 13? × 13? along the c-axis. The gas adsorption studies show that compound 1·13H_2O is stable upon the removal of guest molecules and the desolvated compound absorbed considerable amount of CO_2.
Two novel clusters have been obtained from the solvothermal reactions of 1,10-phenanthroline-2,9 (x = Cl (1), Br (2) -dicarbaldehyde dioxime (H_2phendox) with MnCl 2 · 4H 2 O or anhydrous MnBr 2, and their structures were characterized by elemental analysis, FT-IR, XRD, TGA, MS and single-crystal X-ray diffraction. It crystallizes in trigonal, space group P3_1 / c. X-ray analysis reveals that the neighboring [Mn_3 (μ_3-O) (phendox) _3] + cores are linked by C-H ··· Cl hydrogen bonds and an infinite supramolecular chain along the c- are packed with each other by off-set pp interactions of the aromatic rings on phenox2-. A 3D supramolecular architecture in a honeycomb topology is formed with 1D hexagonal channels in the dimensions of 13? x 13? along the c-axis. The gas adsorption studies show that compound 1 · 13H_2O is stable upon the removal of guest molecules and the desolvated compound presentories of CO_2.
