X-ray powder diffraction data for cobalt tris-ethylenediamine bromide trihydrate and cobalt tris-ethylenediamine iodide hemihydrate

X-ray powder data are given for cobalt tris-ethylenediamine bromide trihydrate, [CO(en)3]Br3 .3H2O, and cobalt tris-ethylenediamine iodide hemihydrate, [Co(en)3] I3.0.5H2O. Refined unit-cell parameters for [Co(en)3]Br3.3H2O are a=11.6949(4) A and c=16.0640(12) A in trigonal space group P3c1 (165) or P3c 1(158) ; volume = 1902.72 A^3; figures of merit: M20=29, F30=55 (0.0138, 40). Refined unit-cell parameters for [Co(en)3]I3.0.5H2O are a=23.3580(14) A, b=13.4739(4) A, and c=11.5421(5) A in orthorhombic space group Pca2 1(29) or Pcam(57); volume =3632.57 A^3 figures of merit: M20=37, F30=81 (0.0058, 64). © 1999 International Centre for Diffraction Data.
