| Abstract: | Reaction of [Ni(CH3CN)6][BF4]2
with [{(5,7-dimethyl-1,8-naphthyridin-2-yl)amino}carbonyl]ferrocene (L)
in acetonitrile affords [NiII2( -F)2(L)4][BF4]2
(1). X-ray structure reveals a
fluoro-bridged Ni2F2
core with each Ni additionally coordinated to four N atoms from the two
chelating ligands. The molecular mass signal is observed at m/z
(z = 2) 848 in the ESI-MS. It is believed that the
bimetallic activation of BF4-, followed by the trifluoroborane exclusion aided by the
ligand L, results in the formation of (1).
The NH∙∙∙F interactions play an important role in the formation and
stabilization of compound (1). |
