Abstract

An x-ray contrast medium containing a multinuclear complex of the formula (M.sub.6 (.mu..sub.3 B).sub.8 A.sub.v).sub.x L.sub.w, wherein M is Mo, W, Re Tc, V, Nb, Ta, Ru, or Fe; .mu..sub.3 B represent a tridentate bridging atom; A is a non-bridging atom; L is a ligand coordinately bonded to at least one M atom; x is a positive integer; and v and w are independently zero or positive integers.
