Abstract: Realisation of the tetragonal phase of Cs2CuCl4 is possible using specific crystal growth conditionsat a temperature below 281K. This work deals with the comparison of the magnetic susceptibilityand the magnetization of this new tetragonal compound with the magnetic behaviour of tetragonalCs2CuCl2.9Br1.1, Cs2CuCl2.5Br1.5, Cs2CuCl2.2Br1.8 and presents consistent results for such quasi2-D antiferromagnets. Structural investigation at low temperature for Cs2CuCl2.2Br1.8 shows nophase transition. The structure remains in the tetragonal symmetry I4/mmm. Furthermore, severalmagnetic reflections corresponding to the propagation vector k = (0, 0, 0) are observed for thistetragonal compound through neutron diffraction experiments below the magnetic phase transitionat TN = 11.3K confirming its antiferromagnetic nature.
