چکیده
The Sn(IV) atom in the centrosymmetric dinuclear title compound, [Sn(2)(C(4)H(9))(4)(C(7)H(3)NO(4))(2)(H(2)O)(2)], exists in a trans-C(2)SnNO(4) penta-gonal-bipyramidal geometry. There are two half-mol-ecules in the asymmetric unit that are completed by inversion symmetry. The crystal studied was a non-merohedral twin with a ratio of 47.3 (1)% for the minor twin component. Bond dimensions are similar to those found in the tetra-gonal polymorph [Huber et al. (1989 ▶). Acta Cryst. C45, 51-54]. O-H⋯O hydrogen-bonding interactions stabilize the crystal packing.

In the centrosymmetric dinuclear complex anion of the title compound, (C(5)H(8)N(3))(2)[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)(2)]·4H(2)O, the Bi(III) atom is eight-coordinated in an N(2)O(6) environment and has a distorted bicapped trigonal-prismatic coordination environment. Extensive inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds lead to the stability of the crystal structure. Inter-acti...
