The structure of the title salt complex, [Fe(C12H8N3O2)2]ClO4·H2O, contains one FeIII cation, two N-(pyridin-2-ylcarbonyl)pyridine-2-carboxamidate (bpca−) anions, one perchlorate anion and one water molecule. The FeIII cation has an approximate octahedral geometry, defined by six N atoms from two bpca− anions. The nearly parallel [dihedral angle = 1.50 (1)°] bpca− anions form two-dimensional supermolecules along the a axis by the way of weak π–π stacking inteactirons [centroid–centroid distances = 3.948 (2), 4.000 (2), 3.948 (2), 3.911 (2), 3.897 (2), 3.984 (2) and 3.929 (2) Å]. Intra- and intermolecular C—H⋯O hydrogen bonding occurs. The water molecule [occupancies 0.520 (5) and 0.480 (5)], two carbonyl O atoms [occupancies 0.622 (7) and 0.378 (7)] and the four perchlorate O atoms [occupancies 0.887 (4) and 0.113 (4)] are each disordered over two positions.

A mixture of methanol and water (1:1, 2 ml) was gently layered on the top of a solution of Fe(ClO4)3.6H2O (46.2 mg, 0.1 mmol) in water (3 ml). A solution of Hbpca = bis(2-pyridylcarbonyl)amine (22.7 mg, 0.1 mmol), in methanol (10 ml) was added carefully as the third layer. Red crystals suitable for X-ray diffraction were obtained after 3 weeks, washed with ethanol and ether, and dried in air.
Lattice water OW1 and OW1' atoms were disordered over two positions with approximate part occupancies of 0.520 (5) and 0.480 (5). Hydrogen atoms on OW1 and OW1' were also treated using the above two part model. The carbonyl oxygen atoms, O1A and O1B, were disordered over two positions with approximate part occupancies of 0.622 (7) and 0.378 (7). The four perchlorate oxygen atoms O5, O6, O7 and O8 were also disordered with approximate part occupancies of 0.887 (4) and 0.113 (4). All of the remaining H atoms were placed in calculated positions and then refined using the riding model with Atom—H lengths of 0.93Å (CH). Isotropic displacement parameters for these atoms were set to 1.2 (CH) times Ueq of the parent atom.
Organic ligands containing nitrogen heteroatoms play an important role in the assembling process of transition-metal complexes (Wu et al., 2009; Xie et al., 2011; Feng et al., 2006; Yu et al., 2010). The N-donor tridentate rigid ligand Hbpca (Hbpca = bis(2-pyridylcarbonyl)amine) has been attracting widespread attention (Kajiwara et al., 2002; Casellas et al., 2005). Mononuclear complexes of the tridentate ligand bpca-, [M(bpca)]+ (M = divalent metal ions] exemplify these types of complexed ligands (Marcos et al., 1989, 1990); Madariaga et al., 1991; Wocadlo et al., 1993).
As a continuation of our studies related to the behaviour of the bpca ligand with FeIII ions, we have synthesized the title salt complex [Fe(bpca)2(ClO4) . H2O]. As shown in Fig. 1, each π–π stacking inteactions [centroid to centroid distances = 3.9475Å, 3.9997Å, 3.9488Å, 3.9107Å, 3.8973Å, 3.9838Å and 3.9287Å, respectively]. The bond lengths for Fe—N vary from 1.902 (2)Å to 1.979 (2)Å, and the angles for N—Fe—N are between 81.65 (9)° and 178.54 (10)°. These bond lengths and angles are in agreement with those found in similar related FeIII compounds (Wocadlo et al., 1993).

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 z 56b8 ero 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. |

Organic ligands containing nitrogen heteroatoms play an important role in the assembling process of transition-metal complexes (Wu et al., 2009; Xie et al., 2011; Feng et al., 2006; Yu et al., 2010). The N-donor tridentate rigid ligand Hbpca (Hbpca = bis(2-pyridylcarbonyl)amine) has been attracting widespread attention (Kajiwara et al., 2002; Casellas et al., 2005). Mononuclear complexes of the tridentate ligand bpca-, [M(bpca)]+ (M = divalent metal ions] exemplify these types of complexed ligands (Marcos et al., 1989, 1990); Madariaga et al., 1991; Wocadlo et al., 1993).
As a continuation of our studies related to the behaviour of the bpca ligand with FeIII ions, we have synthesized the title salt complex [Fe(bpca)2(ClO4) . H2O]. As shown in Fig. 1, each asymmetric unit contains one FeIII cation, two bpca- anions, one perchlorate anion and one lattice water molecule. The bpca ligands are nearly parallel in the structure and form two-dimensional supermolecules by the way of weak π–π stacking inteactions [centroid to centroid distances = 3.9475Å, 3.9997Å, 3.9488Å, 3.9107Å, 3.8973Å, 3.9838Å and 3.9287Å, respectively]. The bond lengths for Fe—N vary from 1.902 (2)Å to 1.979 (2)Å, and the angles for N—Fe—N are between 81.65 (9)° and 178.54 (10)°. These bond lengths and angles are in agreement with those found in similar related FeIII compounds (Wocadlo et al., 1993).
