Pyridinium tetrakis(nitrato-kappa2O,O')(2,2':6',2"-terpyridine-kappa3N)cerate(III) pyridine solvate and bis(methanol-kappaO)tris(nitrato-kappa2O,O')(2,2':6',2"-terpyridine-kappa3N)cerium(III).
The title complexes, (C(5)H(6)N)[Ce(NO(3))(4)(C(15)H(11)N(3))].C(5)H(5)N or (Hpy)[Ce(NO(3))(4)(terpy)].py, (I) (py is pyridine, C(5)H(5)N, and terpy is terpyridine, C(15)H(11)N(3)), and [Ce(NO(3))(3)(C(15)H(11)N(3))(CH(4)O)(2)] or [Ce(NO(3))(3)(terpy)(OHCH(3))(2)], (II), are 11-coordinate. The coordination polyhedron of the Ce atom in (I) is irregular, while that in (II) can be described as an icosahedron with two vertices replaced by one.
