CdCu3(OH)(6)(NO3)(2): An S=1/2 Kagome Antiferromagnet
The cadmium copper hydroxide nitrate, CdCu3(OH)(6)(NO3)(2)center dot 0.5H(2)O, is furnished from oxygenated suspensions of Cu2O in aqueous Cd(NO3)(2). The compound possesses the kagome structural motif and shows no evidence of magnetic ordering to temperatures as low as 5 K, despite exhibiting a Curie-Weiss temperature of Theta = -114 +/- 27 K, thus giving a spin frustration parameter, f = 22.8.
