摘要：

The title complex, [Nb(C7H12N3)(4)]PF6, features chelating hpp anions (hpp is 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]-pyrimidine) that define a distorted dodecahedral coordination geometry based on an N-8 donor set. The Nb atom is situated on a site of symmetry 4, and the PF6- anion has crystallographic fourfold symmetry.
