N2 - A bleach catalyst in the form of a ligand of formula (I); wherein Z1 and Z2 are independently selected from monocyclic or polycyclic aromatic ring structures optionally containing one or more heteroatoms, each aromatic ring structure being optionally,substituted by one or more substituents. Y1 and Y2 are independently selected from C, N, O, Si, P and S atoms. A1 and A2 are independently selected from hydrogen, alkyl, alkenyl and cycloalkyl (each of alkyl, alkenyl and cycloalkyl being optionally substituted, electron donating groups and electron withdrawing groups); i and j are selected from 0, 1 and 2 to complete the valency of the groups Y1 and Y2 each of Q1-Q4 is independently selected from groups of formula (a); wherein 10 > a + b + c + d > - 2; each Y3 is independently selected from O, S, SO, SO2, (G1)(G2)N-C(O), aryl, heteroaryl, P and P(O) each of A3-A6 is independently selected from the groups hereinbefore defined for A1 and A2; ion pairs, complexes and the use of such ligands, ion pairs and complexes in cleaning and/or bleaching compositions are also described.
