Claim:
A transition metal complex of formula (I) or salts thereof: wherein: X is selected from a transitional metal consisting of Pt, Tc, Pd, Mn, Fe, Ru, Au, Re and Rh; n is an integer from 2 to 6; each R 1 is independently selected from halogen, NR′R″R′″ (where each of R′, R″, and R′″ is independently selected from hydrogen, alkyl, cycloalkyl, aryl, heteroaryl, heterocycyl and oxyacyl), optionally substituted acyloxy, optionally substituted alkoxy, SR′R″ (where each of R′ and R″ is independently selected from hydrogen, alkyl, cycloalkyl, aryl, heteroaryl, heterocycyl and oxyacyl), optionally substituted heteroaryl, optionally substituted carbohydrate, or any two R 1 form a malonate, oxalate or glycolate; R 2 is selected from optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted aryl, optionally substituted oxyacyl, optionally substituted acyl, optionally substituted aminoacyl, optionally substituted oxythioacyl, optionally substituted sulfinyl, optionally substituted sulfonyl, optionally substituted oxythioacyloxy, optionally substituted amino, optionally substituted aminothioacyl, optionally substituted carbohydrate, and optionally substituted thioacyl; and wherein each R 3 -R 10 independently represents H, carboxyl, cyano, dihalomethoxy, halogen, hydroxy, nitro, pentahaloethyl, phosphono, phosphorylamino, phosphinyl, thio, sulfinyl, sulfonyl, trihaloethenyl, trihalomethanethio, trihalomethoxy, trihalomethyl, optionally substituted acyl, optionally substituted acylamino, optionally substituted acylimino, optionally substituted acyliminoxy, optionally substituted acyloxy, optionally substituted arylalkyl, optionally substituted arylalkoxy, optionally substituted alkenyl, optionally substituted alkenyloxy, optionally substituted alkoxy, optionally substituted alkyl, optionally substituted alkynyl, optionally substituted alkynyloxy, optionally substituted amino, optionally substituted aminoacyl, optionally substituted aminoacyloxy, optionally substituted aminosulfonyl, optionally substituted aminothioacyl, optionally substituted aryl, optionally substituted arylamino, optionally substituted aryloxy, optionally substituted cycloalkenyl, optionally substituted cycloalkyl, optionally substituted heteroaryl, optionally substituted heterocyclyl, optionally substituted oxyacyl, optionally substituted oxyacylamino, optionally substituted oxyacylimino, optionally substituted oxyacyloxy, optionally substituted oxysulfinylamino, optionally substituted oxysulfonylamino, optionally substituted oxythioacyl, optionally substituted oxythioacyloxy, optionally substituted sulfinyl, optionally substituted sulfinylamino, optionally substituted sulfonyl, optionally substituted sulphonylamino, optionally substituted thio, optionally substituted thioacyl, optionally substituted thioacylamino, or optionally substituted thioacyloxy; or R 9 and R 10 together form an optionally substituted aryl, optionally substituted heteroaryl, or optionally substituted cycloalkenyl.
