A new cobalt compound,{[Co(H2btec)(2,2’-bipy)(H2O)3]·H2O}n (1,H4btec=1,2,4,5-benzenetetracarboxylic acid,2,2’-bipy=2,2’-bipyridine),has been synthesized and charac-terized by single-crystal X-ray diffraction,elemental analysis,IR and X-ray powder diffraction.The crystal belongs to the triclinic system,space group P1,with a=7.230(3),b=11.626(5),c=14.001(6),α=108.12(0)°,β=95.85(0)°,V=1095.33(157)3,C20H20CoN2O12,Mr=539.31,Z= 2,Dc=1.635 g/cm3,μ=0.855 mm-1,F(000)=554,R=0.0427 and wR=0.1042 for 3883 observed reflections (I > 2σ(I)).The title compound features a discrete molecular structure,which is connected with each other through extensive O-H…O hydrogen bonds into an intricate 3D supramolecular network.Additionally,two different patterns of π-π stacking interactions further consolidate the framework.
A new cobalt compound, {[Co (H2btec) (2,2’-bipy) (H2O) 3] · H2O} n (1, H4btec = 1,2,4,5-benzenetetracarboxylic acid, = 2,2’-bipyridine), has been synthesized and charac-terized by single-crystal X-ray diffraction, elemental analysis, IR and X-ray powder diffraction. The crystal belongs to the triclinic system, space group P1, with a = 7.230 (3), b = 11.626 (5), c = 14.001 (6) , α = 108.12 (0) °, β = 95.85 (0) °, V = 1095.33 (157) 3, C20H20CoN2O12, 539.31, Z = 2, Dc = 1.635 g / cm3, μ = 0.855 mm-1, F (000) = 554, R = 0.0427 and wR = 0.1042 for 3883 observed reflections (I> 2σ (I)). features a discrete molecular structure, which is connected with each other through extensive hydroxide ... O hydrogen bonds into an intricate 3D supramolecular network. Additionally, two different patterns of π-π stacking interactions consolidate the framework.
