Semantics, definitions? The description of the electronic structure of main‐group compounds with dative bonds significantly enriched the chemistry of sp block elements. The new viewpoint has proved ...to be a useful guideline for the synthesis of unusual donor–acceptor complexes and for explaining novel molecular structures. New compound classes such as carbones CL2 and borylene complexes (BH)L2 have been found.
The authors explore recent developments in the preparation and chemistry of metallacycles and metallacages via metal-ligand coordination. Post-self-assembly modifications and weak-link modifications ...are among the topics discussed.

It also attacks the central metal in coordination compounds and gives a fluorimetric response. Coordination compounds behave as a sensor for the detection of important ions like CN
