Tetrakis(1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidin-9-ido-κ2N1,N9)niobium(V) hexafluoridophosphate
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 N8 donor set. The Nb atom is situated on a site of symmetry overline{4}, and the PF6− anion...
