A novel two-dimensional organic–inorganic hybrid compound with a (4,6)-lattice-type network: {[Co(H2O)2][Co2(phen)2(btc)2]}n (btc=benzene-1,2,4-tricarboxylate)

A new organic–inorganic hybrid compound {[Co(H2O)2][Co2(phen)2(btc)2]}n 1 has been hydrothermally synthesized and characterized by elemental analyses, IR spectrum, TG analysis and single-crystal X-ray diffraction. Compound 1 crystallizes in the triclinic system, space group P1̄, a=7.7709(16) Å, b=10.572(2) Å, c=12.178(2) Å, α=88.49(3)°, β=77.97(3)°, γ=69.84(3)°, V=917.5(3) Å3, Z=1, R1=0.0571. The compound 1 exhibits a novel two-dimensional network with unusual (4,6)-lattice-type network constructed by [Co2(phen)2(btc)2]2− dimers and the [Co(H2O)2]2+ fragments.
