The asymmetric unit of the title complex, [Zn(H2O)6](C10H5O8)2·2C11H6N2O·2H2O, contains one half of the complex cation with the ZnII ion located on an inversion center, a monovalent 2,4,5-tricarboxybenzoate (1,2,4,5-BTC) counter-anion, a 4,5-diaza­fluoren-9-one (DAFO) mol­ecule and an uncoordinated water mol­ecule. In the crystal structure, O—H⋯O and O—H⋯N hydrogen bonds link the cations, anions and water mol­ecules into a three-dimensional network.

Comment top

Single-crystal X-ray diffraction analyses revealed ZnII is hexa-coordinated and exhibits octahedral coordintion environment supplied by six water molecules (Fig. 1). The O atoms from four coordinated water molecules in the equatorial plane around the ZnII ion form a slightly distorted square-planar arrangement with an average Zn—O bond length of 2.073 (1) Å; the slightly distorted octahedral coordination is completed by the other O atoms at a slightly shorter distance [2.055 (2) Å] in the axial positions. benzene-1,2,4,5-tetracarboxylate (1,2,4,5-BTC) counter-anion, and DAFO molecule are both uncoordinated. Intermolecular hydrogen bonds, O—H···O and O—H···N, extend the ion complex into a three-dimensional supramolecular network structure (Fig. 2, Table 1).

Experimental top

Zinc(II) acetate dihydrate (0.066 g, 0.3 mol), benzene-1,2,4,5-tetracarboxylate (0.055 g, 0.2 mmol), 4, 5-diazafluoren-9-one (0.036 g, 0.2 mmol), sodium hydroxide (0.016 g, 0.4 mmol) and water (14 ml) were placed in a 23 ml Teflon-lined autoclave, and the autoclave was heated at 423 K for 3 d. After cooling slowly to room temperature at a rate of 10 K h-1, colorless crystals were obtained.

Refinement top

C-bound H atoms were treated as riding, with C—H = 0.93Å and Uiso(H) = 1.2 times Ueq(C). O-bound H atoms were located in a difference Fourier map and refined as riding in their as-found relative positions; Uiso(H) = 1.5Ueq(O).

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.
