Tetra-kis(2,4,6-tri-methyl-anilido)tin(IV).

Transamination of Sn(NMe2)4 with H2NMes (Mes is 2,4,6-tri-methyl-phenyl, C9H11) led to the formation of the title compound, [Sn(C9H12N)4] or Sn(NHMes)4, which crystallizes in the tetra-gonal space group P 21 c, with four formula units per unit cell. The mol-ecular structure consists of a central tin(IV) atom, which is surrounded by four NHMes groups. Sn(NHMes)4 possesses crystallographically imposed symmetry. The SnN4 coordination polyhedron is best described as a compressed bis-phenoid.
