title: Poly[(μ(2)-4,4'-bipyridine-κN:N')bis-(μ(4)-cyclo-hexane-1,3-dicarboxyl-ato-κO:O':O'':O''')dizinc(II)].
abstract: The cyclo-hexane-1,3-dicarboxyl-ate dianion in the title three-dimensional coordination polymer, [Zn(2)(C(8)H(10)O(4))(2)(C(10)H(8)N(2))](n), has one carboxyl-ate group in an equatorial position and the other in an axial position of the cyclo-hexane ring, which adopts a chair conformation. The carboxyl-ate groups function as bridges to two adjacent Zn(II) atoms, generating a layer motif. Adjacent layers are linked through the 4,4'-bipyridine N-heterocycle, forming a three-dimensional network; the geometry of Zn(II) is square-pyramidal with the N atom of the N-heterocycle occupying the apical position. The N-heterocycle lies about a center of inversion and is disordered in a 1:1 ratio with respect to the C atoms bearing H atoms.
