 Title    Röntgenograpliische und magnetische Untersuchungen an perowskitverwandten Cyanoverbindungen CsM ,I M III (CN)6 X-Ray and Magnetic Studies of Perovskite-Related Cyano Compounds CsM II M TII (CN)6  
 Abstract    The perovskite-related cyano compounds CsMnCr(CN)6 (Mn = Mn, Zn), CsZnFe(CN)6 and CsMnCo(CN)6 (Mn = Mn-Cu) are characterized by their IR active C N and Mm-CN stretching frequencies, their lattice constants and their magnetic suscept ibilities (4,2-295 K). Except for CsCuCo(CN)6, which is tetragonally distorted, all compounds crystallize cubically face-centered (with lattice constants in the range from 1020 to 1084 pm). The magnetic behaviour indicates low spin Mm and high spin Mn states, supporting the IR evidence for a strictly ordered Mm—CN—Mn arrangement. The compound CsMnCr(CN)6 is ferrimagnetic, with a Neel temperature of T>j = 90 K and an extrapolated spontaneous magnetization of a = 2,30 //B at 0 K. Superexchange interactions via the cyano bridges are considered responsible for the ferrimagnetism observed.
