Abstract

BaCu(C2O42.6 H2O is triclinic, P1, with a = 6.5405(9), b = 9.202(3), c = 10.939(1) Å, α = 85.46(2), β = 79.22(1), γ = 80.45(2), V = 636.99(1) Å3, Z = 2, D0 = 2.14, Dc = 2.465 g. cm−3, R = 0.074, wR = 0.0746 for 2219 significant reflections |F0|≧ 6.0σF0. The barium has eleven coordinations and the coordination polyhedra is a capped antiprism. Six water oxygen atoms are coordinated whereas the other five are coming from the oxalate group. In the unit cell the molecules form a polymeric network. One lattice water molecule belongs to the coordinating water. The barium oxygen distances vary from 2.75 Å to 3.15 Å.
