Zinc picolinate (or ZnPic) is the zinc coordination complex derived from picolinic acid and zinc(II). It has the formula Zn(NC5H4CO2)2(H2O)2. The complex adopts an octahedral molecular geometry, containing two bidentate picolinate ligands (conjugate base of picolinic acid) and two aquo ligands. Additionally, two water of crystallization are present, thus the compound crystallizes with the formula Zn(NC5H4CO2)2(H2O)2·2H2O. It is a colorless solid.
