Two new one-dimensional chain-like coordination polymers,[Cu(H2O)(dpa)- MoO4]·H2O 1 and [Co(H2O)(dpa)MoO4] 2,have been synthesized under hydrothermal reactions. Their structures were determined by single-crystal X-ray diffraction analysis. Crystal data for 1: [Cu(H2O)(dpa)MoO4]·H2O,Mr = 430.71,monoclinic,space group P21/c,a = 9.5469(10),b = 16.6874(17),c = 9.0799(10) ,β = 104.9100(10)°,V = 1397.8(3) 3,Z = 4,Dc = 2.047 g/cm3,F(000) = 852,μ = 2.449 mm-1,the final R = 0.0293 and wR = 0.0638 for 2472 independent reflections (Rint = 0.0338) and 2034 observed reflections with I > 2σ(I). Crystal data for 2: [Co- (H2O)(dpa)MoO4],Mr = 408.09,monoclinic,space group P21/c,a = 10.204(2),b = 18.933(4),c = 6.8875(16),β = 102.195(3)o,Z = 4,V = 1300.5(5) 3,Z = 4,Dc = 2.084 g/cm3,F(000) = 804,μ = 2.262 mm-1,the final R = 0.0357 and wR = 0.0693 for 3022 independent reflections (Rint = 0.0436) and 2286 observed reflections (I > 2σ(I)). Polymer 1 is based on a one-dimensional zigzag chain built up from {Cu(H2O)(dpa)}2+ units bridged through the bidentate {MoO4}2- ligands. The chains extending along the c-axis are arranged alternately with two opposite orientations along the b-axis. The adjacent chains are stably packed together through π-π interactions and exhibit an interesting three-dimensional supramolecular architecture via hydrogen bonding interactions. Polymer 2 based on a one-dimensional zonal chain is built up from {Co(H2O)(dpa)}2+ units linked by the tridentate {MoO4}2- ligands. The ribbons extend along the c-axis. In the bc layers,there are significant interactions of N–H···O–Mo hydrogen bonds and π-π overlaps of dpa ligands between adjacent ribbons.
