Abstract:
A transition metal complex having the Formula (I) wherein M is Fe[II], Fe[III], Co[I], Co[II], Co[III], Mn[I], Mn[II], Mn[III], Mn[IV], Ru[II], Ru[III] or Ru[IV]; X represents an atom or group covalently or ionically bonded to the transition metal M; T is the oxidation state of the transition metal M and b is the valency of the atom or group X; R1, R2, R3, R4, R5, R19, R20, R21, R22, R23, R25, R26 and R28 are independently selected from the group consisting of hydrogen, halogen, hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl and substituted heterohydrocarbyl, wherein when any two or more of R1, R2, R3, R4, and R5 are hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl, said two or more of R1, R2, R3, R4, and R5 can be linked to form one or more cyclic substituents; and R24 and R27 are both halogen, both have two or more carbon atoms or one of R24 and R27 is halogen and the other of R24 and R27 has two or more carbon atoms.
