title: [2,6-Dioxo-1,2,3,6-tetra-hydro-pyrim-idine-4-carboxyl-ato(2-)]bis(pyrazino[2,3-f][1,10]phenanthroline)cobalt(II) dihydrate.
abstract: The title complex, [Co(C(5)H(2)N(2)O(4))(C(14)H(8)N(4))(2)]·2H(2)O, features a slightly distorted octa-hedral geometry for Co due to the sterical requirements of the orotic acid and pyrazino[2,3-f][1,10]phenanthroline ligands. Inter-molecular hydrogen bonding between the uncoordinated water mol-ecules and the ligand stablizes the structure of the complex.
