Two-­ and Three­-Dimensional Hybrid Compounds Formed by 1,2­, 1,3­ and 1,4­Cyclohexanedicarboxylates of Zinc

Abstract

By employing the hydrothermal method, five zinc cyclohexanedicarboxylates (CHDCs) with the compositions, [Zn2(1,4-CHDC)(1,10-phen)4]·(H2O)2(NO3)2 (I), [Zn(1,4-CHDC)] (II), [Zn3(1,3-CHDC)3(4,4′-bipy)] (III), [Zn5(OH)2(1,3-CHDC)4] (IV), and [Zn(1,2-CHDC)] (V), were prepared and characterised. Compound I is a molecular structure while II, III and V have two-dimensional layered structures. Compounds II, III and V are coordination polymers (I0O2) possessing zero-dimensional inorganic connectivity (In, n = 0) and two-dimensional organic connectivity (Om, m = 2). Compound IV is a coordination polymer (I0O3) possessing zero-dimensional inorganic connectivity (In, n = 0) and three-dimensional organic connectivity (Om, m = 3). In all these compounds, the CHDC anions are in the (e,e) conformation except in II, where it has the (a,e) conformation.
