A complex containing a transition metal ion and a plurality of donor ligands each of which is fully coordinated to the transition metal ion and is either a nitrogen donor ligand or a cyclometalated donor ligand, such that at least one of the donor ligands is a cyclometalated donor ligand bears one or more reactive groups connected to at least one of the donor ligands through a linker that includes a chain of four or more atoms. The linker offers advantages that make the complex particularly effective in labeling biomolecules and in multiplex analyses.
