The title mixed-ligand copper(I) complex, [Cu(C18H13N4O5S)(C18H15P)2], was synthesized via solvothermal reaction of [Cu(PPh3)2(MeCN)2]ClO4 and sulfasalazine [systematic name: 2-hydr­oxy-5-(2-{4-[(2-pyridylamino)sulfon­yl]phen­yl}diazen­yl)benzoic acid]. The mononuclear complex displays a trigonal coordination geometry for the Cu(I) atom, which is surrounded by two P-atom donors from two different PPh3 ligands and one O-atom donor from the monodentate carboxyl­ate group of the sulfasalazinate ligand. The latter ligand is found in a zwitterionic form, with a deprotonated amine N atom and a protonated pyridine N atom. Such a feature was previously described for free sulfasalazine. The crystal structure is stabilized by C—H⋯O, C—H⋯N, N—H⋯N and O—H⋯O hydrogen bonds.

Sulfasalazine (systematic name: 2-hydroxy-5-[2-[4-[(2-pyridinylamino)sulfonyl]phenyl]diazenyl]-benzoic acid) is a drug used in treatment of joint diseases such as rheumatoid arthritis and spondyloarthropathies (Neva et al., 2000), as well as in inflammatory bowel diseases (Mansfield et al., 2002). Several crystal structures of metal complexes with sulfasalazine have been reported, with the sulfasalazine exhibiting diversity in its coordination behavior, giving rise to the formation of both monomeric and polymeric structures (Chen et al., 2003, 2008; Kang et al., 2006, 2008a,b; Wang et al., 2005; Yuan et al., 2006).

The copper ion in the title complex displays a trigonal geometry, being linked to two P atoms of two PPh3 ligands, and one O atom of the sulfasalazine ligand (Fig. 1), Due to the great steric effect of the bulky PPh3 ligands, there is a weak bond Cu1—O2 [2.624 (2)Å]. The geometric parameters of sulfasalazine are as expected, and comparable to the reported values (Chen et al., 2008). They also compare well with those of free sulfasalazine (van der Sluis & Spek, 1990) and ethyl-3-[4,5]-dimethoxy-2-(4-methyl-2-pyridylsulphamoyl)phenyl]propionate (Eliopoulos et al., 1983). The sulfasalazine ligand displays a zwitterionic form, with a deprotonated N atom (N3) and a protonated N atom (N4), which is further supported by a strong peak at 1525 cm-1 in the infrared spectrum of the complex (Franklin & Richardson 1980). The crystal structure is stabilized by C—H···O, C—H···N, N—H···N, and O—H···O hydrogen bonds (Table 1 and Fig. 2).

Experimental top

Samples of [Cu(PPh3)2(MeCN)2]ClO4 (0.1 mmol) and sulfasalazine (0.1 mmol) were placed in a thick-walled Pyrex tube (ca 20 cm long). After addition of CHCl3 (1 ml), the tube was frozen with liquid nitrogen, evacuated under vacuum and sealed with a torch. The tube was heated at 353 K for 2 days and then was slowly cooled down to room temperature. Orange-red block crystals were obtained. Yield: 45%. IR (KBr, cm-1): 3444(m), 3050(m), 1627(s), 1586(s), 1525(m), 1463(m), 1434(m), 1362(m), 1291(m), 1269(m), 1198(w), 1169(m), 1135(s), 1083(m), 1002(m), 963(m), 930(w), 848(m), 805(m), 772(m), 746(s), 695(s), 645(w), 610(s), 582(m), 565(m), 510(m).

Refinement top

H atoms bonded to C atoms were positioned geometrically and refined using a riding model with Uiso(H) = 1.2Ueq(C) (C—H = 0.95 Å). The hydroxyl H atom H3 was placed in calculated position, with O—H distance of 0.84 Å, and Uiso(H3) = 1.5Ueq(O3). H atom attached to N4 in the pyridine ring (H1) was located in a difference map and refined freely.
