         wherein E 1  and E 2  are oxygen, 
         wherein the substituent R 1  is selected from the group consisting of branched or unbranched, fluorinated aliphatic hydrocarbons with 1 to 10 C atoms, 
         wherein n=1 to 5, 
         wherein the substituent R 2  is selected from the group consisting of —CN, branched or unbranched aliphatic hydrocarbons with 1 to 10 C atoms, aryl and heteroaryl, and 
         wherein m=0 to at most 5−n. 
       
     
     
         2 . The metal complex according to  claim 1 , wherein the metal M is a main group metal. 
     
     
         3 . The metal complex according to  claim 1 , wherein the metal M is a main group metal of groups 13 to 15 of the periodic table of elements. 
     
     
         4 . The metal complex according to  claim 1 , wherein the metal M is Bi. 
     
     
         5 . The metal complex according to  claim 1 , wherein the metal M is Bi in an oxidation state III. 
     
     
         6 . The metal complex according to  claim 1 , wherein the substituent R 1  is an at least difluorinated substituent. 
     
     
         7 . The metal complex according to  claim 1 , wherein the substituent R 1  is a perfluorinated substituent. 
     
     
         8 . The metal complex according to  claim 1 , wherein the substituent R 1  is a —CF 3  group. 
     
     
         9 . The metal complex according to  claim 1 , wherein the substituent R 1  is a —CF 3  group and the metal M is Bi. 
     
     
         10 . The metal complex according to  claim 1 , wherein the ligand L is attached to the metal atom M by the following form of coordination
