Tetra­kis(tri­ethyl­enediamin-1-ium) dodeca-μ2-chlorido-hexakis(thio­cyanato-κN)hexa-octa­hedro-niobate

The crystal structure of the cluster complex salt, (C6H13N2)4[Nb6(NCS)6Cl12] or (H-DABCO)4[Nb6Cl12(NCS)6] (DABCO = tri­ethyl­enedi­amine or 1,4-di­aza­bicyclo­[2.2.2]octa­ne), comprises octa­hedral Nb6 cluster cores, which are μ2-coordinated by 12 chloride ligands (bridging the octa­hedral edges, inner ligand sphere). Furthermore, each Nb atom is N-bonded to a terminal thio­cyanate ligand (outer ligand sphere). The discrete clusters carry a charge of −4, which is compensated by four monoprotonated DABCO mol­ecules. These are arranged in rows, which are N—H⋯Cl and N—H⋯N hydrogen bonded to the anions and among each other.
