The results of a Rietveld refinement of CsMnCr(CN) 6 · D 2 O neutron powder data (a = 1084.3(1) pm, F4̄3m, Z = 4) and of a neutron single crystal structure refinement of tetragonal NMe 4 Mn II (Cr 0,06 Mn 0,94 ) III (CN) 6 · 8 H 2 O (a = 1065.8(21), c = 1064.6(26) pm, P4/n, Z = 2) at ambient temperature are reported. Single crystal X-ray analyses of the isostructural octahydrate NMe 4 MnCo(CN) 6 · 8 H 2 0 (a = 1062.1 (1), c = 1046.2( 1) pm) and of gel-grown crystals of cubic Mn 3 II [Mn III (CN) 6 ] 2 - 15 H 2 O (a = 1062.6(3) pm, Fm3̄m, Z = 4/3) and Cd 3 [Fe(CN) 6 ] 2 · 15 H 2 O (a = 1067.7(3) pm) were performed as well. The latter “Prussian Blues” are highly disordered and intermediate with respect to cyano-bridging between the above three-dimensional cesium and one-dimensional tetramethylammonium compounds.
