BaCu(C 2 O 4 2 .6 H 2 O is triclinic, P 1 , 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) Å 3 , Z = 2, D 0 = 2.14, D c = 2.465 g. cm −3 , R = 0.074, wR = 0.0746 for 2219 significant reflections | F 0 |≧ 6.0σF 0 . 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.
