Synthesis and characterization of a cadmium(II)–organic supra­molecular coordination compound based on the multifunctional 2-amino-5-sulfo­benzoic acid ligand

Much attention has been paid by chemists to the construction of supra­molecular coordination compounds based on the multifunctional ligand 5-sulfosalicylic acid (H₃SSA) due to the structural and biological inter­est of these compounds. However, no coordination compounds have been reported for the multifunctional amino-substituted sulfobenzoate ligand 2-amino-5-sulfo­benzoic acid (H₂asba). We expected that H₂asba could be a suitable building block for the assembly of supra­molecular networks due to its inter­esting structural characteristics. The reaction of cadmium(II) nitrate with H₂asba in the presence of the auxiliary flexible di­pyridyl­amide ligand N,N′-bis­[(pyridin-4-yl)meth­yl]oxamide (4bpme) under ambient conditions formed a new mixed-ligand coordination compound, namely bis­(3-amino-4-carb­oxy­benzene­sulfonato-κO¹)di­aqua­bis­{N,N′-bis­[(pyridin-4-yl)meth­yl]ox­amide-κN}cadmium(II)–N,N′-bis­[(pyridin-4-yl)meth­yl]oxamide–water (1/1/4), [Cd(C₇H₆NO₅S)₂(C₁₄H₁₄N₄O₂)₂(H₂O)₂]·C₁₄H₁₄N₄O₂·4H₂O, (1), which was characterized by single-crystal and powder X-ray diffraction analysis (PXRD), FT–IR spectroscopy, thermogravimetric analysis (TG), and UV–Vis and photoluminescence spectroscopic analyses in the solid state. The central Cd^II atom in (1) occupies a special position on a centre of inversion and exhibits a slightly distorted octa­hedral geometry, being coordinated by two N atoms from two monodentate 4bpme ligands, four O atoms from two monodentate 4-amino-3-carb­oxy­benzene­sulfonate (Hasba⁻) ligands and two coordinated water mol­ecules. Inter­estingly, complex (1) further extends into a threefold polycatenated 0D→2D (0D is zero-dimensional and 2D is two-dimensional) interpenetrated supra­molecular two-dimensional (4,4) layer through inter­molecular hydrogen bonding. The inter­layer hydrogen bonding further links adjacent threefold polycatenated two-dimensional layers into a three-dimensional network. The optical properties of complex (1) indicate that it may be used as a potential indirect band gap semiconductor material. Complex (1) exhibits an irreversible dehydration–rehydration behaviour. The fluorescence properties have also been investigated in the solid state at room temperature.

Special details

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.
