Copper Complexes with Sulfonamides Derivatives of Natural Amino Acids as Chemical Nucleases

2007

Three new coordination compounds have been prepared by reacting copper salts with sulfonamides derived from amino acids. Their molecular structures have been determined with the aid of single crystal X-ray diffraction. The copper cations are four-coordinated in all cases and the local environment is almost planar. Compound [Cu(ts-gly)(NH3)2]·H2O (1) crystallizes in monoclinic space group P21/c (no 14) with Z = 4 and with unit cell parameters a = 6.0490(12) A, b = 24.719(5) A, c = 9.159(2) A, α = γ = 90°, and β = 94.69(3)°. Compound [Cu(ts-isoleu)(NH3)2] (2) crystallizes in monoclinic space group C2/c (no 8) with Z = 15 and with unit cell parameters a = 30.800(6) A, b = 6.5510(13) A, c = 15.…
