Dimethyl-bis-(pyrazine-2-carboxyl-ato-κ(2)N(1),O)tin(IV).

In the title compound, [Sn(CH(3))(2)(C(5)H(3)N(2)O(2))(2)], the Sn(IV) atom is twice N,O-chelated by two pyrazine-2-carboxyl-ate ligands. The distorted six-coordination is completed by two tin-bound methyl C atoms. The C(2)N(2)O(2) donor set defines a skewed trapezoidal-bipyramidal geometry. Inter-molecular π-π inter-actions between the pyrazine rings [centroid-centroid distance = 3.8112 (13) Å] are observed.
