A comparison is made between the steric influences of a range of zinc hydrotris(pyrazolyl)borates and zinc hydrotris(thioimidazolyl)borates ([Zn(Tp R )Cl], [Zn(Tm R )Cl]; R = Me, i Pr, Ph, t Bu) by using inverse cone angle analysis. The study combines the crystallographic analysis of [Zn(Tm i Pr )Cl] and [Zn(Tm Ph )Cl] with the data previously deposited with the Cambridge Crystallographic Data Centre. Despite efforts to manipulate the reactive pocket around the metal centre in M(Tm R ) complexes, the incorporation of sterically confining substituents onto the framework seems to have a minimal effect at the metal centre unless the group attached is very large.
