摘要

Abstract Two new metal complexes supported by {VO3}n n− chains, [M(dpa)V2O6] (1, M = Zn2+; 2·H2O, M = Cu2+; dpa = 2,2′-dipyridylamine), have been synthesized hydrothermally and characterized by elemental analysis, TG analysis, IR spectroscopy and single-crystal X-ray diffraction. Crystal data: [Zn(dpa)V2O6] 1, Triclinic, P-1, a = 9.663(7) Å, b = 10.617(7) Å, c = 15.114(10) Å, α = 105.678(10)°, β = 104.772(9)°, γ = 94.021(10)°, Z = 2; [Cu(dpa)V2O6]·H2O 2·H2O, Monoclinic, C2, a = 20.543(3) Å, b = 7.2460(9) Å, c = 10.4853(13) Å, β = 111.318(2)°, Z = 4. Complex 1 is constructed from sinusoidal {VO3}n n− chains with {Zn(dpa)}2+ fragments spanning the adjacent troughs and crests into an 1D ribbon-like structure. Complex 2 is built up by linking {VO3}n n− chains via pairs of symmetrical {Cu(dpa)}2+ fragments into a 2D layered structure. The Zn(II) and Cu(II) ions exhibit tetrahedral and square pyramidal coordination environments, respectively. The formation of the two isomers is attributed to the flexibility of {VO3}n n− chains and the different coordination configurations of the two metal ions. There exist significant π–π stacking and hydrogen bonding interactions in complexes 1 and 2.
