An aqueous solution (5 ml) of Cd(ClO4)2.6H2O (0.422 g, 1.0 mmol) was added dropwise to a methanol solution (15 ml) of NaOH (0.041 g, 1.0 mmol), 5-bromosalicylaldehyde (0.202 g, 1.0 mmol) and aminomethanesulfonic acid (0.112 g, 1.0 mmol). The reaction mixture was refluxed for 4 h and added a methanol solution containing 1,10-phenanthroline (0.201 g, 1.0 mmol). The reaction mixture was refluxed for 6 h and then filtered. The resulting yellow filtrate was allowed to stand at room temperature for one month to afford yellow block-shaped crystals. Analysis, calculated for C21H18BrCdN3O5S: C 40.86, H 2.92, N 6.81%; found: C 39.96, H 2.84, N 6.87%.
All H atoms were positioned geometrically and refined as riding, with C—H = 0.93(CH), 0.97(CH2), 0.96(CH3) and 0.93 (OH) Å and Uiso(H)=1.5Ueq(C) for CH3 group and Uiso(H)=1.2Ueq(C, O) for the others.
During the last two decades, the Schiff base complexes containing sulfur and the complexes of amino acid Schiff bases have aroused increasing interest because of their antiviral, anticancer and antibacterial activities (Casella & Gullotti, 1981; Zhang et al., 2005). We have utilized aminomethanesulfonic acid and 5-bromosalicylaldehyde as ligands and investigated their reaction with cadmium acetate. We report here the structure of the title compound.
In the title compound, the CdII atom is six-coordinated by the imine N atom, the phenolate O atom and a sulfonate O atom from the tridentate Schiff base ligand, two N atoms from a phenanthroline ligand and one O atom from a methanol molecule. Thus the CdII atom has a distorted octahedral geometry (Fig. 1). The Cd—O distances are in a range of 1.977 (3)–2.381 (3) Å, and the mean Cd—O bond length is 2.198 (3) Å (Table 1). The Cd—N distances range from 2.084 (3) to 2.135 (3) Å. The Schiff base ligand adopts a κ3O,N,O'-tridentate mode, forming a five-membered ring and a six-membered ring. An O—H···O hydrogen bond between the coordinated O atom of the methanol molecule and an uncoordinated O atom of the sulfonate group and C—H···O hydrogen bonds are observed (Table 2).

During the last two decades, the Schiff base complexes containing sulfur and the complexes of amino acid Schiff bases have aroused increasing interest because of their antiviral, anticancer and antibacterial activities (Casella & Gullotti, 1981; Zhang et al., 2005). We have utilized aminomethanesulfonic acid and 5-bromosalicylaldehyde as ligands and investigated their reaction with cadmium acetate. We report here the structure of the title compound.
In the title compound, the CdII atom is six-coordinated by the imine N atom, the phenolate O atom and a sulfonate O atom from the tridentate Schiff base ligand, two N atoms from a phenanthroline ligand and one O atom from a methanol molecule. Thus the CdII atom has a distorted octahedral geometry (Fig. 1). The Cd—O distances are in a range of 1.977 (3)–2.381 (3) Å, and the mean Cd—O bond length is 2.198 (3) Å (Table 1). The Cd—N distances range from 2.084 (3) to 2.135 (3) Å. The Schiff base ligand adopts a κ3O,N,O'-tridentate mode, forming a five-membered ring and a six-membered ring. An O—H···O hydrogen bond between the coordinated O atom of the methanol molecule and an uncoordinated O atom of the sulfonate group and C—H···O hydrogen bonds are observed (Table 2).
