Abstract
The crystal structure of alpha-CoC2O4 . 2H(2)O suggests a predominant one-dimensional magnetic interaction. The ac powder susceptibility was fitted with a 1D Ising model with g-factors determined by EPR. The ma gnetic heat capacity and chi(p) data delineate a strongly anisotropic 2D Ising system, with J/k similar or equal to -30 K, \J'/J\ similar or equal to 3 X 10(-3), and an antiferromagnetic transition at T-N= 6.23 +/- 0.02 K.
