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

By employing the hydrothermal method, five zinc cyclohexanedicarboxylates (CHDCs) with the compositions, [Zn 2 (1,4‐CHDC)(1,10‐phen) 4 ] · (H 2 O) 2 (NO 3 ) 2 ( I ), [Zn(1,4‐CHDC)] ( II ), [Zn 3 (1,3‐CHDC) 3 (4,4′‐bipy)] ( III ), [Zn 5 (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 ( I 0 O 2 ) possessing zero‐dimensional inorganic connectivity ( I n , n = 0) and two‐dimensional organic connectivity ( O m , m = 2). Compound IV is a coordination polymer ( I 0 O 3 ) possessing zero‐dimensional inorganic connectivity ( I n , n = 0) and three‐dimensional organic connectivity ( O m , 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.
