Claims Analysis
Total Claims: 41
Claim 1
Independent Claim
155 words
A coordination complex compound having the structural formula ##STR35## wherein Me is a transition metal having an atomic number of 21 to 30; W, x, y and Z are groups selected from H and electron donating groups lower alkyl, lower alkoxy, (i.e. alkyls and alkoxys having from 1-8 carbon atoms), --OH and --NH 2 , wherein no more than three H groups are selected; n is an integer 1, 2 or 3; A is a nitrate, sulfate or halide; V is the primary valence of Me; m is the charge of the coordinated species; a is the valence of the Anion A; Me is coordinately bonded with each substituted 1,8-naphthyridine moiety shown in the structural formula solely through one or both ring nitrogen atoms thereof; and when only one such nitrogen atom of each such 1,8-naphthyridine moiety is bonded to Me, n is 2; and each A within the brackets is coordinately bonded with Me.
Claim 2
Dependent Claim
155 words
