Abstract top

In the crystal structure of the title compound, [Cd(C18H10NO2)(NCS)(CH3OH)]n, the CdII atom is O,O'-chelated by the monoanionic carboxylate group and N,N'-chelated by the diazafluorene portion of a symmetry-related ligand. The geometry is seven-coordinate pentagonal bipyramidal. The crystal structure exhibits intermolecular O-H...O hydrogen bonds.

Comment top

4,5-Diazafluorene-9-one and its derivatives are excellent chelating agents (Wang et al., 1998; Xiao et al., 2000; Xu et al., 2003). 4-(4,5-Diazafluoren-9-ylidieneamino)benzoic acid possesses a carboxylic acid substituent, and is then capable of binding through both the diazafluorene as well as the carboxyl parts of the deprotonated carboxylic acid.

In the crystal structure of the title complex (I), the CdII atom shows pentagonal bipyramid coordination. The carboxylate group functions in µ3 bridging mode; it chelates to two metal atoms through the carboxyl and diazafluorene parts and additionally, it uses the oxygen atom of the carboxyl portion to interact with a third metal atom (Fig. 1). Such a bridging mode gives rise to a layer. The coordinated methanol molecular engages in a hydrogen bonding interaction to lead to a three-dimensional hydrogen-bonded structure.

Experimental top

The dafb compound was synthesized by the condensation of 4,5-diazafluorene-9-one with 4-amino-benzoic acid in 1:1 molar ratio in anhydrous ethanol. The title complex was prepared by the reaction of Cd(NO3)2.4H2O (0.308 g, 1.0 mmol), NaSCN (0.081 g, 1.0 mmol) and acid (0.301 g, 1.0 mmol) in 50 ml me thanol; the solution was heated for 2 h. Light yellow crystals were obtained by slow evaporation of the solvent.

Refinement top

H atom bonded to O atom was located in a difference map and refined with O—H = 0.82 Å, and with Uiso(H) = 1.5Ueq(O). Other H atoms were positioned geometrically and refined using a riding model with C—H = 0.95–0.99 Å and with Uiso(H) = 1.2 (1.5 for methyl groups) times Ueq(C).

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.
