Alkaline‐earth based coordination polymers (CPs) with rigid frameworks are promising candidates for future dielectrics. During our attempts to engineer new calcium and strontium dicarboxylates under solvothermal condition, we synthesized six CPs, namely, [Sr( BDC )(DMA)(H 2 O)] ( 1 ), [Ca( ABDC )(DMF)] ( 2 ), [Ca( ABDC )(DMA) 2/3 ] ( 3 ), [Sr( ABDC )(DMF)] ( 4 ), [Sr( OBA )(MF)] ( 5 ) and {[Sr( FBA )(DMA)(H 2 O)].(DMA)(EtOH)(H 2 O)]} ( 6 ) [where, BDC =1,4‐benzenedicarboxylic acid, ABDC= 2‐aminoterephthalic acid, OBA =4,4’‐oxybis(benzoic acid) and FBA= 4,4’‐(hexafluoroisopropylidene)bis(benzoic acid)] and established its full structures using single crystal X‐ray crystallography. A significant structural feature of all the solids was the occurrence of rigid 1D columns made of metal carboxylate coordination. All the solids showed interesting dielectric behaviour and exhibited photoluminescence with blue or bluish‐green emission.
