Abstract
The synthesis, structure and magnetic properties of a new synthetic holland ite, SrxRh4O8 (x approximate to 0.75) are discussed. The compound crystalli zes in the monoclinic space group I2/m, a = 10.4399(5) A, b = 3.0616(1) Ang strom, c = 9.2135(5) Angstrom, beta = 95.261(3)degrees, Z = 2. Electron dif fraction patterns show satellites, indicative of an incommensurate distribu tion of the strontium cations in the channels. The modulation vector was fo und to be (-0.5, similar to0.25, 0.5). The compound shows Pauli-paramagneti c behavior between 5 and 300 K. (C) 2001 Elsevier Science BSI. All rights r eserved.
