| Abstract: | Self-assemble of aqueous solution of the Cu2+/molybdate/glyc-ine system results in {NaCu6(Gly)8(H2O)2]Mo8O26Cu(Gly)2]2}n·n{NaCu6(Gly)8(H2O)2}·n{Mo8O26Cu(Gly)(GlyH)(H2O)2]2} 15nH2O 1, which exhibits the 0-D + 1-D supramolecular framework and in which the copper atoms show three kinds of coordination models: (1) in quadrilateral geometry, (2) in square-pyramidal geometry, and (3) in distorted octahedral geometry. The space group of the compound is P–1, with the lattice parameters: α = 89.036(5)°, β = 89.384(4)°, γ = 88.337(5) °, a = 12.559(4) Å, b = 14.441 (4)Å, c = 23.063(6) Å, and Z = 1. |
