New complexes with the DAFO (4,5-diazafluoren-9-one) ligand of stoichiometry [Ag(DAFO)(P P)]OTf [P-P = dppe, 1,2-bis(diphenylphosphane)ethane; dppp, 1,3-bis(diphenylphosphane)propane; dppph, ortho-bis(diphenylphosphane)benzene; dppcc, 1,2-bis(diphenylphosphane)-1,2-dicarba-c/oso-dodecaborane; dipcc, 1,2-bis(diisopropylphosphane)-1,2-dicarba-nido-dodecaboranel [Ag(DAFO)(P-P*)][P-P* = dppnc, 7,8-bis(diphenylphosphane)-7,8-dicarba-nido-undecaborate(-1); dipnc, 7,8-bis(diisopropylphosphane)-7,8-dicarba-closo-undecaborate(-1)] and [Ag(DAFO)(OTf)L] [L = PPh3; dpccMe, 1-diphenylphosphane-2-methyl-1,2-dicarba-c/oso-dodecaboranel are reported. The structures of the complexes depend on the skeleton of the diphosphane. Most of these compounds are luminescent and their emissions seem to have originated from IL (DAFO) transitions, modified upon coordination to silver.
