%X The structure of the elpasolite Cs2KCr(CN)6 has been determined at 7.0 K by neutron diffraction. 877 unique reflections refined to Rw = 0.020, &#935; = 1.4. The Cr(CN)6 unit is close to regular octahedral coordination geometry, with bond lengths of 207.4(4) for Cr-C and 116.6(6) pm for C-N. The C-Cr-C angles average to 90.0(5)º and the Cr-C-N angles to 178.3(1)º. The magnetic susceptibility as a function of temperature and the magnetization as a function of magnetic field strength correspond to the 4A2g ground term perturbed by a small magnetic exchange effect.
