N2  - The nuclear magnetic resonance of 133Cs (I=7/2) has been studied at room temperature in the isostructural compounds Cs2CuCl4, Cs2CuBr4, Cs2CoCl4 and Cs2ZnCl4. The nuclear quadrupole coupling tensors and the magnetic shift tensors have been determined at the two inequivalent sites of the unit cell for all complexes. A satisfactory description of the quadrupole coupling (νq ≲ 20 kc) with a point charge model is only possible by reducing the charge on the central ion of the MX4 tetrahedron to +1-1. Large isotropic shifts (up to 0.5%) with smaller anisotropic contributions have been found in the paramagnetic compounds. The diamagnetic Cs2ZnCl4 shows shift up to 0.03% relative to CsCl.
