The synthesis of a new asymmetric dinucleating ligand FloH, designed with two sets of metal ion binding groups suited to selective complexation, is reported. The site-directed generation of a heterodinuclear Fe^IIICu^II complex is performed in highyield and purity by using FloH.

A series of neutral pentacoordinate silicon(IV) complexes was synthesized and structurally characterized by NMR spectroscopy (solid state and solution) and single-crystal X-ray diffraction. The compounds studied contain a tridentate dianionic O,N,O or N,N,O ligand, a phenyl ligand, and a (pseudo)halogeno ligand (F, Br, CN, N₃, NCS). These complexes were compared with related compounds that contain a tridentate dianionic S,N,O ligand.

The catalytic efficiency of 11 dinuclear Mn^III compounds with chlorobenzoato ligands has been studied for the disproportionation reaction of H₂O₂. The presence of different ligands and counteranions allowed the analysis of their effects on the catalytic activity.
