Abstract

Hydrothermal reactions of alkaline earth metal nitrates with two ditopic carboxylic acids, trans-1,4-cyclohexanedicarboxylic acid (H₂CDC) and 1,4-phenylenedipropionic acid (H₂PDP), generate two 3-D metal-organic frameworks (MOFs) with empirical formulas [Ca(CDC) (H₂O) ₂]H₂O (1) and [Sr(PDP)(H₂O)] (2), respectively. Compound 1 consists of Ca-COO-H₂O chains cross-linked through the-C₆H10-spacers of the CDC anions, showing slightly open 1-D channels along the crystallographic c axis that accommodate the guest water molecules. Compound 2 exhibits a MOF consisting of wavy 2-D Sr-COO-H ₂O nets linked by-CH₂CH₂C₆H ₄CH₂CH₂-tethers, and the condensed structure appears to arise from conformational flexibility of the ligand spacer.
