Due to excellent catalytic activity and high atomic utilization rate, single atom catalysts (SACs) have become a rising star in the field of nanocatalytic medicine. Heteronuclear dual-atom (HDACs) retain advantages monoatomic catalysts, more optionally regulated coordination environment, possess favorable synergistic effects between different active sites, can break through restriction adsorpti...

An overview of organometallic or coordination multinuclear titanium complexes published so far is given herein. The majority these compounds are supramolecular homonuclear complexes, which listed according to their nuclearity and usually synthesized through one-pot procedures; the others mostly early-late heteronuclear complexes. We have attempted outline a systematic classification architectur...
