Claim:
A metal complex compound of formula (1a) [L n Me m X p ] z Y q (1a), wherein Me is manganese, titanium, cobalt, nickel or copper, X is a coordinating or bridging radical, n and m are each independently of the other an integer having a value of from 1 to 8, p is an integer having a value of from 0 to 32, z is the charge of the metal complex, Y is a counter-ion, q=z/(charge of Y), and L is a ligand of formula (2) wherein Q is CR 10 , R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and R 10 are each independently of the others hydrogen; unsubstituted or substituted C 1 -C 18 alkyl or unsubstituted or substituted aryl; cyano; halogen; nitro; —COOR 11 or —SO 3 R 11 ; —SR 12 , —SO 2 R 12 or —OR 12 ; —NR 13 R 14 ; —(C 1 -C 6 alkylene)-NR 13 R 14 ; —N ⊕ R 13 R 14 R 15 ; —(C 1 -C 6 alkylene)-N ⊕ R 13 R 14 R 15 ; —N(R 12 )—(C 1 -C 6 alkylene)-NR 13 R 14 ; —N[(C 1 -C 6 alkylene)-NR 13 R 14 ] 2 ; —N(R 12 )—(C 1 -C 6 alkylene)-N ⊕ R 13 R 14 R 15 ; —N[(C 1 -C 6 alkylene)-N ⊕ R 13 R 14 R 15 ] 2 ; —N(R 12 )—N—R 13 R 14 or —N(R 12 )—N ⊕ R 13 R 14 R 15 , wherein R 11 is in each case hydrogen, a cation or unsubstituted or substituted C 1 -C 18 alkyl or unsubstituted or substituted aryl, R 12 is in each case hydrogen or unsubstituted or substituted C 1 -C 18 alkyl or unsubstituted or substituted aryl, and R 13 , R 14 and R 15 are each independently of the other(s) hydrogen or unsubstituted or substituted C 1 -C 18 alkyl or unsubstituted or substituted aryl, or R 13 and R 14 , together with the nitrogen atom linking them, form an unsubstituted or substituted 5-, 6- or 7-membered ring which may contain further hetero atoms.
