According to recent research from Nanjing, People's Republic of China, "In the title compound, [Zn(C7H4FO2)(2)(C5H6N2)(2)] or [Zn(fa)(2)(2-pa)(2)] (Hfa is 2-fluorobenzoic acid and 2-pa = pyridin-2-amine), the asymmetric unit contains one Zn-II cation, two fa ligands and two 2-pa ligands, wherein the Zn-II displays a distorted tetrahedral geometry, being surrounded by two monodentate fa ligands with Zn-O distances of 1.962 (2) and 1.976 (3) angstrom, and by two 2-pa ligands with distances involving pyridyl N atoms of 2.069 (2) and 2.056 (2) angstrom."
"The F atoms of the fa ligands are equally disordered over two sites, viz. the 2- and 6-positions of fa," wrote ...
