title: Dichlorobis(3,5-dimethylpyrazole-N2)methylphenyltin(IV)
abstract: The title compound, [SnCl(2)(CH(3))(C(6)H(5))(C(5)H(8)N(2))(2)], was obtained by reaction of dichloromethylphenyltin(IV) and 3, 5-dimethylpyrazole (dmpz) in chloroform, and was recrystallized from acetone. The structure consists of octahedral all-trans [SnMePhCl(2)(dmpz)(2)] molecules, with the Sn atom coordinated to two C [Sn-C 2.127 (5) and 2.135 (4) A], two Cl [Sn-Cl 2.5753 (8) A] and two N atoms [Sn-N 2.357 (3) A]. The dmpz ligands, bound to the metal through their unprotonated N atoms, form weak intra- and intermolecular hydrogen bonds with the Cl ligands via their NH groups, giving rise to a polymeric chain along the c axis.
