In the title coordination polymer, [Zn5(μ3-OH)2(1,4-CDC)4]n (1,4-CDCH2 = 1,4-cyclohexanedicarboxylic acid) or [Zn5(C8H10O4)4(OH)2]n, the asymmetric unit comprises one half of an octahedrally coordinated ZnO6 complex unit (site symmetry overline1) and two five-coordinate ZnO5 complex units, together with two μ3-bridging hydroxido ligands and four 1,4-CDC ligands (comprising two whole molecules and four inversion-related half-molecules). The ZnO6 unit consists of four carboxylate O donors (two bridging) and two hydroxido O donors (both bridging three Zn centres) [Zn—O range 2.065 (3)–2.125 (3) Å]. Each of the ZnO5 units [one capped tetrahedral, the other square-pyrimidal; Zn—O range 1.928 (3)–2.338 (3) Å] has one hydroxido O donor and four carboxyl O donors from three different 1,4-CDC carboxylate O donors (one bridging). Infinite (ZnO)n inorganic chains run parallel to the a axis and are interconnected by the organic ligands into a three-dimensional structure.
