"Can One σ*-Antibonding Orbital Interact with Six Electrons of Lewis Bases? Analysis of a Multiply Interacting σ* Orbital" #chempaperaday 97

This paper is really interesting. Synthesis of the tin complex is very straightforward. But, the structure and the interpretation is exciting. To be honest, when I first saw the paper, I said "there is nothing special about it. I am sure thousands of complexes have similar structures and same interactions can be seen." But, after reading the discussion, (obviously) I changed my opinion. Also, I like the honesty of the authors

"We wish to report here the first example which is beyond our aforementioned common knowledge of dative bonds."
