Abstract: In the title compound, [Sn(CH3)2(C5H3N2O2)2], the SnIV atom is twice N,O-chelated by two pyrazine-2-carboxylate ligands. The distorted six-coordination is completed by two tin-bound methyl C atoms. The C2N2O2 donor set defines a skewed trapezoidal-bipyramidal geometry. Intermolecular [pi]-[pi] interactions between the pyrazine rings [centroid-centroid distance = 3.8112 (13) Å] are observed.
