Abstract

The binuclear complex [NBuⁿ ₄]₄[Cr₂(ox) ₅]· 2CHCl₃ has been prepared by an ion-exchange procedure employing Dowex 50WX2 cation-exchange resin in the butylammonium form and potassium tris(oxalato)chromate(in). The dimeric complex was characterised by a crystal structure determination: monoclinic, space group C2/c, a = 29. 241 (7), b = 15. 192(2), c = 22. 026(5) Å , β , = 94. 07(1)° , Z = 4. The magnetic susceptibility (300-4. 2 K) indicated that the chromium(m) sites were antiferromagnetically coupled (J = -3. 1 cm^-1).
