Abstract

Experimental photoelectron and computational results show diniobium-carbon (Nb2Cn) clusters to coexist in multiple structural isomers: three-dimensional geometries, planar rings, and linear chains. Threedimensional clusters having up to five carbons are formed preferentially with Nb-Nb bonding, whereas only Nb-C bonding is observed experimentally at six carbons. Clusters consisting of an odd number of atoms are also observed with linear geometries. The larger binary clusters (n ≤ 7) display properties similar to those of pure carbon clusters. We provide evidence for niobium substitution of carbon atoms.
