In the title compound, [CoFe(CH)(CHFO)(HO)], the central Co atom has an octa-hedral coordination geometry defined by two chelating tri-fluoro-methyl-β-diketone ferrocene ligands and two aqua ligands, with the latter in a disposition. The Cp rings in both ferrocene groupings are close to eclipsed. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into [100] chains.

Benefiting from the tunable singlet-triplet energy gap and aggregation-induced emission characteristics, two-photon active photosensitizers L2b and L2c showed relatively strong intersystem crossing facilitating 1O2 generation and cell apoptosis with near-infrared excitation.
