Crystal Growth, Structure, Magnetism, and Electrochemical Properties of Hexavalent Strontium Ruthenium Oxyhydroxide.

ABSTRACT: We report the crystal growth and comprehensive studies including crystal and electronic structure and magnetic and electrochemical properties of the hexavalent ruthenium oxyhydroxide Sr₃Ru₂O₈(OH)₂ prepared through a low-temperature hydrothermal method. Single crystals and powder samples of this phase are isolated by optimizing the Sr-(OH)₂·8H₂O to KRuO₄ ratio while maintaining a high base concentration. The new structure consists of a rare five-coordinated Ru^VI featuring isolated trigonal prisms and crystallizing in a noncentrosymmetric tetragonal system. Isolated Ru polyhedra leading to a large spatial distance (∼5 Å) between the Ru metal centers render the compound paramagnetic despite strong antiferr
