Abstract
Abstract A complex is described of the formula: TX.sub.2 (RNC).sub.y wherein TX 2 is the inorganic host in which T is selected from the group consisting of titanium, zirconium, hafnium, vanadium, niobium, tantalum, molybdenum and tungsten and mixtures thereof, and X is a chalcogenide selected from the group consisting of sulfur, selenium and tellurium, and RNC is the organic guest wherein R is an alkyl or aryl alkyl radical of from 1 to 18 carbon atoms and y is a number ranging from about 0.10 to about 2.0. These new complexes are afforded by the intercalation of organic isonitriles within the layered structure of Group IVb, Vb, molybdenum and tungsten transition metal dichalcogenides.
