RESUMO
The structure of the title compound, (C16H17N2)3[Co(CN)6]·5H2O, consists of three 3,4,7,8-tetra-methyl-1,10-phenanthrolin-1-ium cations, a [Co(CN)6](3-) anion and five water mol-ecules of crystallization, one of which is disordered over two sets of sites in a 0.587â (15):0.413â (15) ratio. The [Co(CN)6](3-) anion exhibits an octa-hedral geometry. In the structure, cations and anions are linked alternatively through O-Hâ¯O, O-Hâ¯N, N-Hâ¯O and N-Hâ¯N hydrogen bonds, π-π inter-actions [centroid-centroid distances = 3.523â (2)-4.099â (2)â Å] and van der Waals forces, forming a three-dimensional supra-molecular network.
RESUMO
In the structure of the title complex, {[CeFe(CN)(6)(H(2)O)(2)]·2H(2)O}(n), the Ce(III) and Fe(III) atoms exhibit square anti-prismatic [CeN(6)(H(2)O)(2)] (site symmetry m2m) and octahedral [FeC(6)] (site symmetry 2/m) coordination geometries, respectively. The metal atoms are linked alternately through the cyanide groups, forming a three-dimensional framework in which the {Ce(2)Fe(2)(CN)(4)} puckered square unit is the basic building block. The crystal packing is enforced by O-Hâ¯O and O-Hâ¯N hydrogen bonds, including the uncoordinated water molecule which is located on a mirror plane.
RESUMO
The asymmetric unit of the title complex, (C(12)H(9)N(2))(3)[Fe(CN)(6)]·C(2)H(5)OH·3H(2)O, consists of two half [Fe(CN)(6)](3-) anions located on inversion centers, three 1,10-phenanthrolin-1-ium cations, [Hphen](+), an ethanol and three water solvent mol-ecules. The average Fe-C and C-N bond lengths are 1.942â (6) and 1.154â (3)â Å, respectively, while the Fe-C-N angles deviate slightly from linearity with values ranging from 177.8â (2) to 179.7â (2)°. The Fe(III) atoms adopt a distorted octa-hedral geometry. All the species are linked through O-Hâ¯N, N-Hâ¯O and O-Hâ¯O hydrogen-bonding inter-actions, resulting in a three-dimensional supra-molecular network.
