✦ Synopsis

The substituted tritertiary arsine, 2-chloroethylbis(3-dimethylarsinopropyl)arsine, forms Ni(trias)Xz (X = Cl, Br, I), which are assigned tetragonal pyramidal pentacoordinate structures. The Pd(trias)CIz species is best assigned as a planar [Pd(trias)C?]Cl coordination moiety. Both [Co(trias)Br] z [CoBr,] and [Co(trias)Br] C104 contain pseudotetrahedral cations, but [Co(tr&),] (CL'O,), is unlike any fourcoordinate or six-coordinate cobalt(U) entity and is assigned a pentacoordinate structure containing a tridentate and a bidentate ligand. l%e donor properties of trias are compared to that of similar tridentate ligands.
