A metal-organic coordination polymer [Zn2.5(phen)(BDC)2(OH)]2 (phen = 1,10- phenanthroline, BDC = benzene-1,4-dicarboxylic acid) 1 has been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction, elemental analyses and IR spectroscopy. The complex crystallizes in the triclinic system, space group P1 with a = 11.199(2), b = 11.593(2), c = 11.865(3) , α = 99.330(1), β = 111.506(1), γ = 104.804(1)°, V = 1328.4(5) 3, Dc = 1.722 g/cm3, Z = 1, Mr = 1377.82, F(000) = 692, μ(MoKα) = 2.306 mm-1, S = 1.093, R = 0.0281 and wR = 0.0756 for 4179 observed reflections (I > 2σ(I)). The coordination polyhedron around Zn(II) can be described as a tetrahedron, trigonal bipyramid and octahedron. It is worth noting that the crystal structure of 1 is composed of tetranuclear zinc clusters linked by {ZnO6} units.
