The structure of the title compound, (C₁₆H₁₇N₂)₃[Co(CN)₆]·5H₂O, consists of three 3,4,7,8-tetramethyl-1,10-phenanthrolin-1-ium cations, a [Co(CN)₆]³⁻ anion and five water molecules of crystallization, one of which is disordered over two sets of sites in a 0.587 (15):0.413 (15) ratio. The [Co(CN)₆]³⁻ anion exhibits an octahedral geometry. In the structure, cations and anions are linked alternatively through O—H⋯O, O—H⋯N, N—H⋯O and N—H⋯N hydrogen bonds, π–π interactions [centroid–centroid distances = 3.523 (2)–4.099 (2) Å] and van der Waals forces, forming a three-dimensional supramolecular network.

Comment top

In the past few years, hexacyanometallates [M(CN)₆]^3- (M = Fe, Co, Cr) have been employed usually as building blocks to react with the second metal ions in the presence of organic ligands, forming several types of bimetallic assemblies with various dimensional structures and interesting properties (Andruh et al., 2009; Tokoro et al., 2011). However, the development of hexacyano- and lanthanide-based assemblies has been somewhat hampered by the tendency of the lanthanide ions to adopt higher coordination numbers, and their ability to easily adapt to a given environment. Recently, we used the [Co(CN)₆]^3- presursor to react with lanthanide ion Ce³⁺ and the chelated ligand 3,4,7,8-tetramethyl-1,10-phenanthrolin (tmphen), to construct organic-inorganic hybrid materials. Unexpectedly, a new ion-pair compound (Htmphen)₃Co(CN)₆.5H₂O without Ce³⁺ ions was obtained instead.

The structure of the title compound, (C₁₆H₁₇N₂)₃Co(CN)₆.5H₂O, consists of three 3,4,7,8-tetramethyl-1,10-phenanthrolin-1-ium cations, a [Co(CN)₆]^3- anion and five water molecules of crystallization (Fig. 1). The six-coordinated [Co(CN)₆]^3- unit exhibits an octahedral geometry, in which the mean Co—C and C—N bond distances are 1.946 (4) Å and 1.151 (2) Å, respectively, while the Co-CN bonds are almost linear with the maximum deviation from linearity of 2.9°. The cations and anions are linked alternatively through hydrogen bonds (Table 1), π···π interactions (centroid-to-centroid distances = 3.523 (2)–4.099 (2) Å) and van der Waals forces to form a three-dimensional supramolecular network (Fig. 2). The structure of the title compound is different from those of hexacyanide-based family of pentanuclear clusters {[M(tmphen)₂]₃[M'(CN)₆]₂]} (M = Cr, Mn, Co, Ni, Zn; M' = Co, Cr, Fe) (Shatruk et al., 2007) and octacyanide-based helical chains [Ln(tmphen)₂(DMF)_n][M(CN)₈].xsolvents (Ln = Sm, Pr; n = 2, 5; M = Mo, W) (Qian et al., 2011) reported previously.

Experimental top

The title compound was prepared at room temperature by slow diffusion of an ethanol solution containing Ce(NO₃)₃.6H₂O (0.10 mmol) and 3,4,7,8-tetramethyl-1,10-phenanthrolin (0.20 mmol) into an aqueous solution of K₃[Co(CN)₆].H₂O (0.10 mmol). After two weeks, colourless plate-like crystals were obtained.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > 2sigma(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
