Magnetic interactions in 1.
Strong AF interactions J along the vertical chains and weak ferromagnetic interactions J′ between the chains. An antiferromagnetic second nearest neighbour interchain coupling J″ leads to frustration of the already weak interchain coupling, leading to the highly 1D properties observed experimentally.
