Group 6 transition metal halide clusters with the general formula [M6X8Y6]2- (X, Y = Cl, Br, I)  have been studied extensively because of their unique electrochemical properties and long-lived excited states. Using solvent-free methods, we are interested in preparing new sulfonate and carboxylate derivatives of these clusters and incorporation of these clusters into 2D and 3D network structures. One approach utilized the direct reaction of (Bu4N)2[M6Cl8Cl6] with various silver salts (AgY) in sealed tubes at ~200�C, producing the desired [M6Cl8Y6]2- product. A second, indirect approach reacted the lightly-coordinated (Bu4N)2[M6Cl8(CF3SO3)6] with various (Bu4N)carboxylate salts, again in sealed tubes at ~160�C. We have shown that various metal halide cluster derivatives can be prepared at relatively low temperature in the absence of solvent.
