metal-organic compounds
The U atom in the crystal structure of the title compound, [U(NO3)2O2(C21H19O2P)], shows hexagonal-bipyramidal coordination, as the nitrate and carboxylate groups function as chelates. The oxo O atoms occupy the axial sites of this uncommon coordination geometry.

In the title compound, [Zn(CH5N3S)2(H2O)2](C4H3O4)2·2H2O, the ZnII ion lies on a centre of symmetry and is coordinated by two pairs of N and S atoms from two symmetry-related thiosemicarbazide ligands and two O atoms from two water molecules in a distorted octahedral geometry. In the crystal structure, the components are effectively linked together by electrostatic interactions and hydrogen bonds of the O—HO, N—HO and N—HS types into a three-dimensional network.
