Tetrakis(1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidin-9-ido-κ(2) N (1),N (9))niobium(V) hexafluoridophosphate
The title complex, [Nb(C(7)H(12)N(3))(4)]PF(6), 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 [Image: see text], and the...
