Synthesis, molecular structure, and magnetic properties of [CuLNi(H2O)2LCu][ClO4]2·4H2O [H2L =N,N′-bis(3-amino-2,2-dimethylpropyl)oxamide] and its trinickel homologue

Abstract

The compounds [MLNi(H2O)2LM][ClO4]2·4H2O [M = Cu or Ni; H2L =N,N′-bis(3-amino-2,2-dimethylpropyl)oxamide] were prepared and characterized by means of structural, magnetic and spectroscopic measurements. The crystals of both compounds are triclinic, space group P[1 with combining macron] and Z= 2, with a= 12.080(1), b= 13.054(1), c= 14.775(2)Å, α= 101.97(1), β= 90.82(1) and γ= 101.88(1)°, for M = Cu and a= 12.099(5), b= 13.060(4), c= 14.750(7)Å, α= 101.98(3), β= 90.28(4) and γ= 102.25(3)° for M = Ni. The structural unit of both complexes consists of trinuclear dipositive cations, two perchlorate anions and four lattice water molecules. The central and terminal metal ions are antiferromagnetically coupled, J= 90(1) cm–1 in the case of M = Cu.
