Abstract

Two new three-dimensional open frameworks, {[Cu4V 13IVV5VO42(NO 3)(C3H10N2)8] ·10H2O}n (1) and {[Cu4V 12IVV6VO42-(SO 4)(C3H10N2)8] ·10H2O}n (2), have been hydrothermally synthesized. Structural analysis indicates that both complexes are isomorphic and are constructed from a cluster anion [V18O42(XO y)]8- (X = N, y = 3 or X = S, y = 4) and a bridging cation [Cu(C3H10N2)2]2+ with classical ACO topological structure. Complex 1 crystallizes in the tetragonal space group P4/nnc, with a = b = 15.1128(12) Å, c = 18.670(3) Å, V = 4264.1(9) Å3, Z = 2. Complex 2 is tetragonal, P4/nnc, a = b= 15.1131(10) Å, c = 18.588(10) Å, V = 4245.5(7) Å3, Z = 2. Both complexes keep the same topological framework with channels of dimensions 7.5 × 7.5 Å running along the [001] direction.
