A solution of FeCl2 (200 mg, 1.00 mmol) in CH3OH (20 ml) was slowly added to a solution of 1,3,5-triazinane-2,4,6-trione (260 mg, 1.95 mmol) in CH3OH (10 ml). The resultant pale green solution was stirred under N2 for 2 h at 323 K and then filtered. After addition of diethyl ether (20 ml), the filtrate was cooled to 253 K. Microcrystalline material was collected after 24 h and dried under vacuum (yield: 237 mg, 53%). Green blocks suitable for X-ray diffraction were obtained in 2 d by slow diffusion of diethyl ether into a dilute solution of the title complex in methanol. The assigned structure was substantiated by elemental analysis; calculated for C6H18N6FeO13: C 16.47, H 4.12, N 19.21%; found: C 16.43, H 4.18, N 19.17%.
The structure was solved using direct methods followed by Fourier synthesis. Non-H atoms were refined anisotropically. The water/nitrogen H atoms were located and isotropically refined, with the O—H/N—H and H···H for water molecules distances restrained to 0.84 (1) and 1.37 (2) Å, respectively. All other H atoms were placed in calculated positions (C—H = 0.93 or 0.97 Å), and were included in the refinement using the riding-model approximation. Uiso values were set equal to 1.5Ueq(parent atom) for water/nitrogen H atoms and to 1.2Ueq(parent atom) for all other H atoms.
Recently we reported a series of one-dimensional helical Ag(I) compounds containing 8-hydroxyquinoline coordinating groups (Cai et al., 2001 and 2003). As a part of the structural studies of the compounds involving the oxygen-nitrogen chelating ligand (Cai et al., 2005), here we report the synthesis and structure of the compound, pentaaqua(1,3,5-triazinanyl-2,4,6-trione)iron(II) 1,3,5-triazinanate-2,4,6-trione dihydrate, namely [Fe(C3H2N3O3)(H2O)5]+(C3H2N3O3)- 2H2O (Scheme 1).
Fig.1 shows that the molecule of [Fe(C3H2N3O3)(H2O)5]+(C3H2N3O3)- 2H2O consists of one cation [Fe(C3H2N3O3)(H2O)5]+, one anion (C3H2N3O3)- and two water molecules. The FeII atom exhibits a FeNO5 octahedral coordination geometry arising from one N-bonded 1,3,5-triazinanyl-2,4,6-trione molecule and five O atoms of water molecules. The uncoordinated 1,3,5-triazinanyl-2,4,6-trione anion and uncoordinated water molecules interact with the cation through O—H···O, O—H···N and N—H···O hydrogen bonds (Table 1), generating a three-dimensional network.

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. |

Recently we reported a series of one-dimensional helical Ag(I) compounds containing 8-hydroxyquinoline coordinating groups (Cai et al., 2001 and 2003). As a part of the structural studies of the compounds involving the oxygen-nitrogen chelating ligand (Cai et al., 2005), here we report the synthesis and structure of the compound, pentaaqua(1,3,5-triazinanyl-2,4,6-trione)iron(II) 1,3,5-triazinanate-2,4,6-trione dihydrate, namely [Fe(C3H2N3O3)(H2O)5]+(C3H2N3O3)- 2H2O (Scheme 1).
Fig.1 shows that the molecule of [Fe(C3H2N3O3)(H2O)5]+(C3H2N3O3)- 2H2O consists of one cation [Fe(C3H2N3O3)(H2O)5]+, one anion (C3H2N3O3)- and two water molecules. The FeII atom exhibits a FeNO5 octahedral coordination geometry arising from one N-bonded 1,3,5-triazinanyl-2,4,6-trione molecule and five O atoms of water molecules. The uncoordinated 1,3,5-triazinanyl-2,4,6-trione anion and uncoordinated water molecules interact with the cation through O—H···O, O—H···N and N—H···O hydrogen bonds (Table 1), generating a three-dimensional network.
