| Abstract: | Trigonal Crystallizing Metal(II) Hexacyanoferrates(II) M2IIFe(CN)6] According to X-ray powder diagrams, Ca2Fe(CN)6], Cd2Fe(CN)6], Zn2Fe(CN)6] · 2 H2O, Pb2Fe(CN)6] and the firstly described compounds Zn2Fe(CN)6] · 2 NH3 and Sn2Fe(CN)6] crystallize trigonal containing one formula unit in the unit cell. Ca2Fe(CN)6] and Cd2Fe(CN)6] are belonging to the space group D —P3 1m, the other compounds to D —P3 m1. The latters are described as coordination polymers with a coordination number 4 for Zn and 3 for Sn and Pb, respectively. |
