Abstract Tetraethylammonium tribromo[2-(2-chloro-5-nitrostyryl)benzoselenazole] platinate (II), [(C2H5)4N][PtBr3(C15H9ClN2O2Se)], is monoclinic, in space groupP21/c, witha=9.496(2),b=20.321(7),c=15.166(3)Å,β=100.18(1)°,V=2880(2)Å3,M r =928.72,Z=4,D x =2.141 g cm−3, λ(MoKα)=0.71073 Å,μ=104.1 cm−1,F(000)=1752,T=298 K. The structure was solved by direct methods and refined toR=0.032 for 2626 unique observed reflections withI〉3σ(I). The [Pt(nsbse)Br3)] unit has square-planar geometry about the Pt atom, with the nsbse coordinated to the Pt through the N of the selenazole ring. The ligand molecule is non-planar, with a dihedral angle of 61.6(2)° between the benzoselenazole and phenyl rings. The dihedral angles between the PtBr3 plane and the benzoselenazole and phenyl planes are 105.2(1) and 80.7(1)°, respectively.
