Abstract
The cubic crystal structure of the title compound, [NaNd(C14H21N3O5PS)4]n, is composed of one-dimensional polymeric chains propagating in [100], built up from [Nd(C14H21N3O5PS)4]− anions and sodium cations functioning as linkers. In the complex anion, the Nd3+ ion has an eightfold coordination environment formed by the sulfonyl and phosphoryl O atoms of four bidentate chelating N-(dimorpholinophosphoryl)benzenesulfonamidate ligands: the resulting NdO8 polyhedron can be described as intermediate between dodecahedral and square antiprismatic. The sodium ion adopts an NaO4 tetrahedral geometry arising from four monodentate benzenesulfonamidate ligands. The resulting crystal structure is unusual because it contains substantial voids (800 Å3 per unit cell), within which there is no evidence of included solvent.
