✦ Synopsis

A powder neutron diffraction study of the crystal structure of (\left.\mathrm{K}{2} \mid \mathrm{RuCl}{s} \mathrm{NO}\right)) in the electronic groundstate is presented in the temperature range from 25 to (295 \mathrm{~K}), confirming the orthorhombic space group Prma. Neither a structural nor a magnetic phase transition has been observed. A shortening of the axial (\mathrm{Ru}-\mathrm{Cl}_{2}) bond occurs with increasing temperature, while the (\mathrm{Ru}-\mathrm{N}) bond gets longer. The metal to chloride bonds do not change uniformly. (1) 1993 Academic Press. Inc.

Variable-temperature powder neutron di4raction data demonstrate that FeV 2 S 4 undergoes a transition to a long-range magnetically ordered state at 135(7) K, in agreement with magnetic susceptibility data. High-resolution neutron di4raction data collected at 1.9 K reveal that magnetic ordering resul
