Abstract:
1. A hexa-coordinate iron (II) complex comprising a compound of formula (I): wherein each R A is selected from: wherein each of R each R each R each of which may be optionally substituted with one or more substituents selected from the group consisting of C L m represents the charge of the compound of formula (I) and is 0, +1, or +2; and when m is +1 or +2, the iron (II) complex comprises at least one counter ion to counterbalance the charge of the compound of formula (I); with the following provisos: (a) when A is then at least one of L 1 and L 2 must be selected from the group consisting of CO and CNR, wherein R is as defined above; (b) when each R A is not each R R each of which is unsubstituted or is substituted with one or more substituents selected from the group consisting of C 1 -C 8 alkyl, C 1 -C 8 alkoxy, and halogen atoms; L L m is not +2; (c) when each R A is not each R each R L L m is not +2; and and the iron(II) complex does not comprise BF (d) when each R A is not each R each of R L L m is not +2; and and the iron (II) complex does not comprise the anion BPh (e) when each R A is not wherein each R 2 and R 3 is H, and n is the integer 1; each R each R each of which is unsubstituted or substituted with one or more substituents selected from the group consisting of C L L m is not +2; and the iron (II) complex does not comprise the anion BF (f) when each R A is not wherein each R 2 and R 3 is H and each n is the integer 1; each R each R L L m is not +2; and the iron (II) complex does not comprise the anion BF
