ABSTRACT OF THE DISCLOSURE Disclosed herein are organometallic ternary charge transfer com-plexes of the formula (I) a(RCl)?MClm?b(Ar) (I) wherein RCl is an inorganic chloride which contains at least one oxygen and/or sulfur atom and is capable of forming a complex salt a(R)?MCl(a+m) with the Lewis acid MClm, such as NOCl, MClm is a Lewis acid metal chloride, such as BCl3, AlCl3, GaCl3, TlCl3, AsCl3, SbCl3, SbCl5, FeCl3, SnCl4, TiCl4 and ZrCl4, Ar is an aromatic compound, such as naphthalene, anthracene, thio-phene, furan and benzene which is unsubstituted or substituted with lower alkyl, halogen, diloweralkylamino, oxo or lower alkoxy, m is an integer representing the valency of the metal M, a is an integer selected such that the sum of a and m does not ex-ceed the coordination number of the metal M of the given valency, b is 0.5, 1 or 2 The inorganic chlorides RCl are typically NOCl, SOCl2 or POCl3. The complexes of formula (I) are intensely colored solids, stable to dissociation. They are reasonably conducting, thus are useful as organic conductors, and being intens-ely colored, are valuable as dyes and coloring materials. |
