N2 - 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.
