title: Bis(5-methyl-pyrazine-2-carboxyl-ato)-diphenyl-tin(IV).
abstract: In the mol-ecule of the title compound, [Sn(C(6)H(5))(2)(C(6)H(5)N(2)O(2))(2)], two O and one N atoms from the two 5-methyl-pyrazine-2-carboxyl-ate ligands and one C atom of a phenyl group form a distorted square-planar arrangement in the equatorial plane around the Sn atom, while the distorted octa-hedral coordination is completed by an N atom of one of the 5-methyl-pyrazine-2-carboxyl-ate ligands and a C atom of the other phenyl group in the axial positions. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
