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.
