(Received 15 March 2012; accepted 24 March 2012; online 4 April 2012)

Single crystals of the title heterometallic compound, [Fe(C₁₂H₈N₂)₃][Cr(NCS)₄(C₁₂H₈N₂)]₂·3CH₃CN·H₂O or [Fe(Cphen)₃][Cr(NCS)₄(phen)]₂·3CH₃CN·H₂O, were prepared using the one-pot open-air reaction of iron powder, Reineckes salt and 1,10-phenanthroline (phen) in acetonitrile. The asymetric unit consists of an [Fe(phen)₃]²⁺ cation, two [Cr(phen)(NCS)₄]⁻ anions, three acetonitrile solvent molecules and a water molecule. The Fe and Cr atoms both show a slightly distorted octahedral FeN₆ and CrN₆ coordination geometry with adjacent angles in the range 79.67 (12)–95.21 (12)°. No classical hydrogen bonding involving the water molecule is observed.

Comment top

Recently we have reported that the Reineckes salt, (NH)₄[Cr(NCS)₄(NH₃)₂]^.H₂O, could be exploited as a source of building blocks or metalloligands in the direct synthesis of heterometallic Cu/Cr and Co/Cr compounds with amines and Schiff-base ligands (Nikitina et al.., 2009; Semenaka et al.., 2011). In the present work, we report that the reaction of iron powder, Reineckes salt and 1,10-phenanthroline (phen) in acetonitrile solution has afforded a single crystals of the novel heterometallic Fe/Cr compound. The asymetric unit of title compound consists of slightly distorted octahedral [Fe(phen)₃]²⁺ cation and two [Cr(phen)(NCS)₄]^- anion blocks as well as solvate acetonitrile and water molecules (Fig. 1). In complex cation iron centers are in elongated octahedral coordination environment with six nitrogen atoms phen ligands. The bond lengths of Fe–N vary in the range 1,959 (3) – 1,980 (3) Å which is in the range usually found in other iron-phen derivatives (Alonso et al., 2005). The cis and trans N–Fe–N bond angles vary from 82,27 (12)° to 95.21 (12)° and from 172.90 (12)° to 174.04 (11)°, respectively. The Cr(III) ions have N6 donor set formed by two N atoms from phen, which are replaced NCS groups in initial anions of Reineckes salt, and two NCS-groups in the equatorial plane and by two another NCS-groups at the axial positions. The axial Cr–N bond lengths are vary from 1,962 (3) to 2,077 (3) Å. The cis and trans N–Cr–N bond angles vary from 79,80 (11)° to 94,97 (12)° and from 170,61 (12)° to 174,77 (12)°, respectively. The thiocyanate groups are almost linear, bond angles N–C–S are in a narrow range: from 178.1 (3) ° to 179.3 (4)°.

Experimental top

Iron powder (0.07 g, 1.25 mmol), NH₄[Cr(NCS)₄(NH₃)₂]^.H₂O (0.443 g, 1.25 mmol), NH₄NCS (0.190 g, 2.5 mmol), phen^.H₂O (0.496 g, 2.5 mmol) and acetonitrile (15 ml) were heated to 50–60° and stirred magnetically until total dissolution of the iron was observed (4,5 h). The resulting red solution was slowly evaporated at room temperature until dark-red crystals suitable for crystallographic study were formed. The crystals were filtered off, washed with dry PrⁱOH and finally dried in vacuo at room temperature. Yield: 0.25 g.

Special details top

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