Abstract

A 1:2:2:6 molar ratio of Cd(NO₃)₂ • 4H ₂O, Cu(NO₃)₂ • 3H₂O, tris(2-aminoethylamine) (tren) and NH₄NCS in aqueous solution at room temperature affords trinuclear complex of the type [Cu₂Cd(tren) ₂(NCS)₆] (1). The complex has been characterised using microanalytical, spectroscopic and magnetic results. X-ray diffraction measurements have been made to define the coordination sphere and long-range structure. 1 consists of two pentacoordinated copper(II) occupied by tren N atoms and one bridging SCN^- N atom of the central trans-[Cd(NCS) ₄(SCN)₂]^4- molecular ion which bridges by the 1,3-thiocyanate. Each of these trinuclear units are engaged in intra as well as intermolecular N-H⋯S hydrogen bonding. Variable-temperature magnetic study shows no significant magnetic interactions among the metal ions.
