This seven valence electron discrete cluster is a moderately-soluble coordination complex of the known, seven electron, extended structure (Nb3Cl8)x. The solid state structure consists of a triangular cluster with one face-capping µ3-Cl, three edge-bridging µ-Cl ligands on the opposite face, and three terminal N-bonded CH3CN ligands per Nb. The average Nb-Nb, Nb-(µ3-Cl), and Nb-(µ-Cl) distances for one of the four independent cluster cores in the unit cell are 2.811[1] Å, 2.438[9] Å, and 2.427[3] Å, respectively, and the average Nb-(µ-Cl)-Nb angle is 70.8[1]°. These values are compared to those of other discrete triniobium clusters and triniobium chloride extended structures with the Nb3(µ3-X)(µ-X)3XnL9−n incomplete metallacubane structure.
