 Title    Crystal Structure Refinement and Single Crystal 81 Br Zeeman NQR Study of KHgBr 3 H 2 0  
 Abstract    Three 81 Br NQR resonance lines of KHgBr 3 H 2 0 were detected between 77 K and room temperature. From the Zeeman effect measurement on a single crystal the nuclear quadrupole coupling constants (e 2 qQ/h) and the asymmetry parameters (r/) were obtained, which are 228.42 MHz and 0.005, 226.24 MHz and 0.005, and 108.76 MHz and 0.465 for e'qQIh and rj at 295 K, respectively. Large deviations of the observed directions of electric field gradient tensors from the directions expected from previous X-ray results have been found. With the present X-ray redetermination, 1 Br NQR and structure are in good agreement. The structure and bonding in the compound are discussed.
