Abstract:
A compound having a general structure selected from the group consisting of structure 1 and structure 2: wherein each said structure 1 and said structure 2:each said single solid line represents a covalent bond; each said double solid line represents a bond having varying degrees of covalency; each said dashed line represents a bond having a varying degree of covalency and a varying degree of coordination; said M is a metal atom covalently bonded to each said O oxygen atom, and bonded with varying degrees of covalency and coordination to each said N nitrogen atom; said X1 and said X2 are each a univalent anionic ligand covalently bonded to said metal atom; said X3 is a single anionic ligand covalently bonded to said metal atom; said R1 and said R2 are each a univalent radical covalently bonded to a different one of said N nitrogen atoms; said R3 is a univalent radical covalently bonded to said C carbon atom of said â€”CHR3â€” of said (C6)1â€”CHR3â€”Nâ€” bridging unit; said R4 is a univalent radical covalently bonded to said C carbon atom of said â€”CHR4â€” of said â€”Nâ€”CHR4â€”(C6)2 bridging unit; each said R5 through R8 is a univalent radical covalently bonded to a different one of said C carbon atoms of said (C6)1 first aromatic group; each said R9 through R12 is a univalent radical covalently bonded to a different one of said C carbon atoms of said (C6)2 second aromatic group; and said Y is a divalent radical covalently bonded to and bridging between both of said N nitrogen atoms.
