Abstract
The planar transition metal compounds NN′-ethylenebis(salicylideneaminato)metal(II)[MII(salen)] where the metal ion is cobalt(II), nickel(II), or copper(II), react with the halides SnX4 and SnX2(where X = Cl or Br) to form 1 : 1 adducts. Characterisation of these adducts using magnetic data, and diffuse reflectance and i.r. spectroscopy indicates a retention of planarity about the transition-metal ion. Structures are suggested for the adducts. A mechanism is put forward to explain the metal-exchange reaction observed in polar solvents for the adducts CoII(salen)SnX4, leading to the compounds SnX2(salen).Keywords
