Abstract:
Two new one-dimensional Cu II coordination polymers (CPs) containing the C 2 h -symmetric terphenyl-based dicarboxylate linker 1,1′:4′,1′′-terphenyl-3,3′-dicarboxylate (3,3′-TPDC), namely catena -poly[[bis(dimethylamine-κ N )copper(II)]-μ-1,1′:4′,1′′-terphenyl-3,3′-dicarboxylato-κ 4 O , O ′: O ′′: O ′′′] monohydrate] , {[Cu(C 20 H 12 O 4 )(C 2 H 7 N) 2 ]·H 2 O} n , (I), and catena -poly[[aquabis(dimethylamine-κ N )copper(II)]-μ-1,1′:4′,1′′-terphenyl-3,3′-dicarboxylato-κ 2 O 3 : O 3′ ] monohydrate] , {[Cu(C 20 H 12 O 4 )(C 2 H 7 N) 2 (H 2 O)]·H 2 O} n , (II), were both obtained from two different methods of preparation: one reaction was performed in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) as a potential pillar ligand and the other was carried out in the absence of the DABCO pillar. Both reactions afforded crystals of different colours, i.e. violet plates for (I) and blue needles for (II), both of which were analysed by X-ray crystallography. The 3,3′-TPDC bridging ligands coordinate the Cu II ions in asymmetric chelating modes in (I) and in monodenate binding modes in (II), forming one-dimensional chains in each case. Both coordination polymers contain two coordinated dimethylamine ligands in mutually trans positions, and there is an additional aqua ligand in (II). The solvent water molecules are involved in hydrogen bonds between the one-dimensional coordination polymer chains, forming a two-dimensional network in (I) and a three-dimensional network in (II).
