Abstract

Abstract Two new Np(V) azide complexes with electroneutral N-donor ligands of terpyridine derivatives have been synthesized and structurally characterized: [(NpO2)(Cl-Terpy)(N3)(H2O)] (1) and a centrosymmetric dimer [(NpO2)(EtO-Terpy)(N3)]2·2CH3OH (2). The coordination polyhedra of Np atoms in compounds are pentagonal bipyramids with “yl” oxygen atoms in apical positions. The equatorial plane of the bipyramid in complex 1 is formed by: a nitrogen atom from an anion, three nitrogen atoms from an electroneutral Cl-Terpy ligand and an oxygen atom of a water molecule. The equatorial plane of bipyramids in dimer 2 is formed by five nitrogen atoms: two atoms from two anions [N3]− and three atoms from EtO-Terpy. In compound 1, the anion [N3]− acts as a monodentate ligand, and in compound 2, the anion [N3]− is a bidentate-bridging ligand.
