(a) Contents of the asymmetric unit of Cubar with the atom-numbering scheme (ORTEP3; Farrugia, 1997). Displacement ellipsoids are drawn at 50% probability level. (b) The shape of CuII coordination polyhedron: each Cu atom is coordinated to five O atoms – three from water molecules and two from barbiturate anions. Prepared using Mercury (Macrae et al., 2006). |
