Coordination and structural properties of encumbering 6-mesityl-2-picolinate complexes

Abstract

In an effort to enforce a sterically hindered environment in transition-metal and main-group 2-picolinate complexes, the synthesis of the encumbering derivative 6-mesityl-2-picolinate (^Mespic) is presented. The coordination and structural properties of ^Mespic are demonstrated with a range of transition-metal and main-group fragments. The 6-position mesityl group of ^Mespic is shown to alter both the primary and secondary coordination spheres of metal centers relative to the ubiquitous and unencumbered parent 2-picolinate anion.
