title: Tetra-kis(nitrato-κ(2)O,O')[N,N'-1,4-phenyl-enebis(pyridine-4-carboxamide)-κN(1)](4-{[4-(pyridine-4-carboxamido-κN(1))phen-yl]carbamo-yl}pyridin-1-ium)neodymium(III).
abstract: In the title compound, [Nd(NO(3))(4)(C(18)H(15)N(4)O(2))(C(18)H(14)N(4)O(2))], the Nd(III) centre is located on a twofold axis and exhibits a ten-coordinated distorted bicapped square-anti-prismatic geometry. The pyridinium NH H atom is disordered over the two ligands. Adjacent mononuclear clusters are linked through N-H⋯O and N-H⋯N hydrogen-bonding inter-actions, generating layers in the (102) plane.
