Aqua­{N-[(4-methyl­phen­yl)sulfon­yl]glycinato(2−)-κ²N,O}(1,10-phenan­throline)copper(II)

In the title complex, [Cu(C₉H₉NO₄S)(C₁₂H₈N₂)(H₂O)], the Cu^II ion is coordinated in a distorted square-pyramidal geometry by the two N atoms from a 1,10-phenanthroline ligand, one N atom from the deprotonated amino group of an N-tosyl­glycinate ligand, one O atom from the carboxyl­ate part of the N-tosyl­glycinate ligand and a water O atom. Inter­molecular O—H...O hydrogen bonds involving the water H atoms link neighboring mol­ecules into supra­molecular chains along [010]. Weak π–π stacking inter­actions [centroid–centroid distances of 3.456 (1) and 3.691 (1) Å] between the benzene rings of 1,10-phenanthroline ligands of adjacent mol­ecules extend the chains into a layer structure parallel to (001).

S1. Comment

As a kind of amino acid derivatives, the N-protected amino acid plays an important role in participating in the process of the life activity. The substitution of an Ar—SO₂-group on the amine nitrogen of amino acids, such as glycine and B-alanine, increases the coordination donors behavior of amino acids to three types of O, N donors from carboxyl, sulfoxyl and amine respectively, which may lead to different coordination modes, thus is of great interest in studying the coordination chemistry of N-sulfonyl- amino acids for many chemical workers (Ma et al., 2008; Liang et al., 2004; Battaglia et al., 1983; Menabue et al., 1991; Antolini et al., 1985). In order to continue the research, we synthesized the title complex [Cu(C₉H₉NO₄S)(C₁₂H₈N₂)(H₂O)] and characterized it by an elemental analysis and a single-crystal X-ray diffraction analysis.

The molecular structure and crystal packing diagram of the title compound are presented in Figs. 1 and 2, respectively. The asymmetric unit contains one copper cation, one Ts-gly anion, one phen molecule and one coordinated water molecule. The central copper ion adopts a distorted square-pyramidal geometry by two N(N2, N3) atoms of the 1,10-phenanthroline ligand, one N(N1) and one O(O1) atoms of the Ts-gly ion occupying basal site, while the apical position is occupied by another O atom of a water molecule. The Cu—O1 bond distance of 1.9269 (13) Å is shorter than those of other N-protected glycine complexes (1.933–1.967 Å) [Battaglia, et al., 1983; Antolini, et al., 1985; Menabue & Saladini, 1991]. Furthermore, the C—O bond distance for the coordinated O atom (1.282 (2) Å) is significantly longer than that for the uncoordinated O atom (1.233 (2) Å), which is similar to previously reported complexes (Battaglia, et al., 1983; Antolini, et al., 1985).

Intermolecular hydrogen bonds involving the water H atoms, O(5)—H(1W)···O(2)ⁱ, O(5)—H(2W)···O(4)ⁱⁱ (Table 1), link the neighboring molecules into one-dimensional supramolecular chains. Weak π-π stacking interactions between benzene rings of 1,10-phenanthroline ligands from adjacent molecules (centroid distances of 3.456Å and 3.691 Å) extend the one-dimensional chains into a two-dimensional layer structure.

S2. Experimental

To a solution of Ts-gly (1 mmol) in water-DMF 1:1 (10 ml), an aqueous solution (5 ml) of CuCl₂.2H₂O (1 mmol) and a solution of 1,10-phenanthroline (1 mmol) in ethanol (95%, 5 ml) was added. After refluxing for 12 h at 343 K, the mixture was filtered off while hot. The green single crystals suitable for a X-ray analysis were obtained by slow evaporation of the filtrate at room temperature after 41 days. IR(KBr): 3442(vs), 1638(vs), 1586(s), 1518(s), 1493(m), 1434(s), 1382(vs), 1348(m), 1319(m), 1243(vs), 1132(vs), 1112(vs), 1078(s), 1007(s), 967(s), 940(m), 847(s), 820(m), 723(s),663(s), 589(s), 545(m) cm^-1.

S3. Refinement

H atoms bonded to C were placed geometrically and treated as riding with C—H = 0.93–0.97 Å and U_iso(H) = 1.2U_eq(C). The water H atoms were found in difference Fourier maps and refined with O—H = 0.85 Å and U_iso(H) = 1.5U_eq(O).

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.
