Die Kristallstruktur von Calciumhexacyanoferrat(II)- Hexamethylentetramin-Wasser(1/1/6) Ca2 [Fe(CN)6] · C6H12N4 · 6H2O The Crystal Structure of Calciumhexacyanoferrate(II)- Hexamethylenetetramine-Water(1/1/6) Ca2[Fe(CN)6] · C 6H12N4 · 6H2O
Meyer, Hans-Jürgen; Pickardt, Joachim
Ca2[Fe(CN)6]•Ct,H12N4-6H20 crystallizes in the monoclinic space group B2lb with a = 1130,2(4), b = 1373,5(4), c = 1353,0(4) pm and y = 97,17°. The X-ray single crystal structure determination converged at R - 0.055 (2057 reflections). Each of the four Fe(CN)6 octahedra (Z = 4) in the unit cell is coordinated by six Ca atoms with mean NCYAN —Ca distances of 253.5(3) pm. The Ca atoms are bridged by hexamethylenetetramine and water molecules
