(2,6-Bis[(dimethylamino)methyl]-phenyl-N(2),C(1),N(6))diphenyltin(II) bromide monohydrate.

In the title compound, [Sn(C(6)H(5))(2)(C(12)H(19)N(2))]Br.H(2)O, the Sn(IV) atom lies on a twofold axis and is coordinated by a C and two N atoms from the 2,6-bis[(dimethylamino)methyl]phenyl ligand in a tridentate fashion and by two phenyl groups. The resulting geometry is intermediate between square pyramidal and trigonal bipyramidal, with three C atoms in equatorial and the two N atoms in axial positions. The main deformation from ideal trigonal-bipyramidal geometry is seen for the N-Sn-N angle [152.18 (7) degrees]. The Br(-) anion and the water solvate molecule are on an inversion centre and twofold axis, respectively. They form an infinite chain of Br.H-O-H.Br hydrogen bonds [Br.O 3.529 (2) A] without contributing to the primary coordination sphere of the Sn atom.
