20 - 016No Van Vleck-Type Paramagnetism in In2ZrBr6. — Single crystalsof the title compound are grown by solid state reaction of thoroughly purified(sublimation) InBr and ZrBr4 (2:1 molar ratio, 300 ◦C, 31 d). The producedsamples are diamagnetic (χmol = -2.27 [10−4 emu/mol]). Thus, previous claimsthat In2ZrBr6 exhibits Van Vleck-type paramagnetism are disproved. Basedon structural data of higher accuracy (tetragonal, space group P4/mnc, Z = 2)density functional band structure calculations are performed which give noevidence for indirect coupling of In and Zr mediated by bromine. — (JANSEN,MARTIN; WAGNER, NORBERT; BECKER, MICHAEL; WEDIG, ULRICH;J.
