A study of the NbPdSe system has afforded a new phase, Nb2Pd3Se8. The structure of this phase has been established through single-crystal X-ray measurements. The compound crystallizes in space group D92h-Pbam with two formula units in a cell of dimensions a = 15.074(6), b = 10.573(4), c = 3.547(2)Å. In this unusual structure there are two chains of edge-sharing selenium trigonal prisms centered by niobium atoms. These chains conjoin through two types of palladium atoms-square planar and square pyramidal-each coordinated by selenium atoms. As a consequence of this conjunction tunnels extending along c result. Electrical conductivity measurements indicate that this material is a metallic-semiconductor.
