Abstract top

In the title hydrated molecular salt, [Fe(C12H8N2)3](C9H5N4O)2·0.5H2O, the water molecule site is half-occupied. The Fe-N bond lengths within the octahedral tris-chelate [Fe(phen)3]2+ ion (phen is 1,10-phenantroline) are indicative of a low-spin d6 electronic configuration for the metal ion. The C-N, C-C and C-O bond lengths in the polynitrile anions indicate extensive electronic delocalization. In the crystal, the components are linked through O-H...N hydrogen bonds, forming [100] chains, as well as through Coulombic interactions.

Comment top

1,10-Phenanthroline (phen) is a widely utilized chelating ligand in coordination chemistry and a lot of complexes with phen as a ligand have been reported (Hoshina et al., 2000; Hwang & Ha, 2006; Zhou & Guo, 2007). Recently, Cai et al. (2012) has reported the structure of a complex with [Fe(phen)3]2+ as cation and 1,1-dicyano-2-ethoxy-2-oxoethanide as counter-ion. We report here the synthesis and crystal structure of the title compound, in which a polynitrile anion acts as counter-ion.

The structure of (I) is composed of a discrete [Fe(phen)3]2+ cations, uncoordinated tcnoet anions and water molecules of crystallization (Fig. 1).

Six nitrogen atoms from three bidentate phen ligands form a distorted octahedron around the iron atom with a mean Fe1—N bond length of 1.972 (18) Å. The main distortion from the octahedral geometry is observed in the values of the angles subtended by phen at the metal atom (82.36 (7)°, 82.50 (8)° and 83.02 (8)° for N1—Fe1—N2, N4—Fe1—N3 and N6—Fe1—N5, respectively) which deviate significantly from the ideal value of 90°. Each phenanthroline ligand is coplanar to within 0.04 Å. The average value of dihedral angle between pairs of phenanthroline planes is 82,1(3)°. The carbon-carbon and carbon-nitrogen intra-ring bond lengths agree with those observed in other metal complexes with chelating phen (Hoshina et al., 2000; Aparici Plaza et al., 2007; Cai & Zhan, 2012).

Examination of the intermolecular contacts in the crystal structure of (I) reveals that the main contacts are associated with O—H···N hydrogen bonds involving the water H atoms and those of the N atoms of the CN groups of the tcnoet anions containing atoms O1 (Table 1). In the crystal, this leads to the formation of an infinite one-dimensional {[(H2O)(tcnoet)2]2-}n anionic chains (Fig. 2), which interact with the cationic entities [Fe(phen)3]2+ and the tcnoet anions involving atoms O2 via coulombic forces.

Due to the presence of the supplementary π electron systems of the cyano groups, the tcnoet ligands of (I) present a strong electronic delocalization, as indicated by C—N, C—C and C—O bond lengths.

Experimental top

Potassium 1,1,3,3-tetracyano-2-ethoxypropenide (Ktcnoet) was prepared by reaction in ethanol of 1,1-diethoxy-2,2-dicyanoethene with malononitrile and potassium t-butoxide as described in Ref (Middleton & Engelhardt, 1958). Under aerobic conditions, an aqueous solution of Fe(BF4)2.6H2O (0.034 g, 5 ml) was slowly added to an ethanolique solution of 1,10-phenanthroline (0.020 g, 5 ml). To the resulting red soluion was added dropwise an aqueous solution of the polynitrile potassium salt Ktcnoet (0.045 g, 10 ml). The final solution was filtered and the filtrate was allowed to evaporate for few days at r.t. offorded red prisms of (I).

Refinement top

Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 to 0.97 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2 to 1.5 U(C).

The water H-atoms were placed in calculated positions on the basis of hydrogen bonding and their temperature factors tied by a factor of 1.5 times. As the oxygen atom displayed extremely large temperature factors, the refinement of its occupancy was attempted. This refined to nearly 0.5; the occupancy was then set to exactly 0.5.

The two ethyl groups are disordered over two positions in a 1:1 ratio. The C—C distance was restrained to 1.54±0.01 Å. For each group, the pair of O—C distances were restrained to within 0.01 Å of each other. The anisotropic temperature factors of the C atoms of the groups as well as those of the water molecule were tightly restrained to be nearly isotropic.

Omitted from the refinement were several reflections affected by the beamstop: (0 0 2), (0 1 0), (0 - 1 1), (1 - 1 1), (0 1 1), (0 1 2), (-1 1 0), (-1 1 1), (0 2 0), (0 0 1) and (0 0 3).
