Claim 1
Independent Claim
141 words
A COMPOUND HAVING AN AROMATIC HYDROCARBON MOLECULE COMPOSED OF SIX TO 18 CARBON ATOMS, SAID HYDROCARBON BEING SELECTED FROM THE GROUP CONSISTING OF BENZENE, BIPHENYL, NAPHTHALENE, HYDROCARBON SUBSTITUTED BENZENES, HYDROCARBON SUBSTITUTED BIPHENYLS AND HYDROCARBON SUBSTITUTED NAPHTHALENES, AID HYDROCARBON BEING CORRDINATED TO A SINGLE GROUP VIIB METAL ATOM, THE COMPOUND BEING STABILIZED BY ADDITIONAL COORDINATION WITH A CYCLOPENATADIENYL RADICAL SELECTED FROM THE CLASS CONSISTING OF THE CYCLOPENTADIENYL RADICAL AND HYDROCRABON SUBSTITUTED CYCLOPENTADIENYL RADICALS HAVING FROM 6 TO 13 CARBON ATOMS WHICH EMBODY A RING HAVING THE GENERAL CONFIGURATION FOUND IN CYCLOPENTADIENE, WHEREIN THE CARBON ATOMS COMPRISING A BENZENE RING WITHIN THE AROMATIC HYDROCARBON CONTRIBUTE SIX ELECTRONS TO THE METAL ATOM, AND THE CARBON ATOMS COMPRISING A CYCLOPENTADIENE RING WITHIN THE CYCLOPENADIENYL RADICAL CONTRIBUTE FIVE ELECTRONS TO THE METAL ATOM, THEREBY GIVING THE METAL THE ELECTRON CONFIGURATION OF THE NEXT HIGHER RARE GAS.
