Differing degrees of five-coordination for similar tin atoms in the polymetallic complex [(OC)3Fe![[upper bond 1 start]](https://www.rsc.org/images/entities/char_e010.gif)

Abstract
The unusual iron–bistin complex, [(OC)3Fe(µ-Ph2Ppy)(S
nPh2)(µ-Cl(S
nClPh2)], obtained by silicon–tin exchange from a Si–Fe–Sn precursor, contains two tin atoms showing different degrees of five-coordination, a unique feature of relevance to hypercoordination of main-group elements.
