Hydrogen-bonded network structures in dipyridinium, bis(2-methylpyridinium), bis(3-methylpyridinium) and bis(4-methylpyridinium) dioxidobis(oxydiacetato)uranate(VI).

ABSTRACT: Four complexes containing the [UO(2)(oda)(2)](2-) anion (oda is oxydiacetate) are reported, namely dipyridinium dioxidobis(oxydiacetato)uranate(VI), (C(5)H(6)N)(2)[U(C(4)H(4)O(5))(2)O(2)], (I), bis(2-methylpyridinium) dioxidobis(oxydiacetato)uranate(VI), (C(8)H(8)N)(2)[U(C(4)H(4)O(5))(2)O(2)], (II), bis(3-methylpyridinium) dioxidobis(oxydiacetato)uranate(VI), (C(8)H(8)N)(2)[U(C(4)H(4)O(5))(2)O(2)], (III), and bis(4-methylpyridinium) dioxidobis(oxydiacetato)uranate(VI), (C(8)H(8)N)(2)[U(C(4)H(4)O(5))(2)O(2)], (IV). The anions are achiral and are located on a mirror plane in (I) and on inversion centres in (II)-(IV). The four complexes are assembled into three-dimensional structures via N-H...O and C-H...O interactions. Compounds (III) and (IV) are isomorphous; the [UO(2)(oda)(2)](2-) anions
