Syntheses, crystal structures and characterization of divalent transition metal sulfonate complexes with o-phenanthroline
摘要:
Three new complexes, namely [Cu(phen)(L)(H2O)(2)]L.H2O 1, [M(phen)(2)(H2O)(2)]2L-6H(2)O [M = Co(2), Ni(3)], where, HL = 4-methylbenzenesulfonic acid and phen = o-phenanthroline, have been synthesized. The crystal structures were determined by X-ray diffraction method and refined by full-matrix least-squares methods to R = 0.0535 and wR = 0.1492 using 3567 reflections with I > 2sigma(I) for 1; R = 0.0388 and wR = 0.1223 using 3844 reflections with I > 2sigma(I) for 2; and R = 0.0401 and wR = 0.1222 using 3425 reflections with I > 2sigma(I) for 3. 1 Consists of cationic species [Cu(phen)(L)(H2O)(2)](+), in which Cu(H) ion is five-coordinated by two nitrogen atoms of o-phenanthroline, two water molecules and one sulfonate oxygen atom. The cations and the non-coordinating sulfonate anions are linked by hydrogen bonds to form infinite chains. Complexes 2 and 3 are isostructral compounds. Each of them consists of cationic species [M(phen)(2)(H2O)(2)](2+), in which metal ion is six-coordinated by four nitrogen atoms from two o-phenanthroline molecules and two water oxygen atoms. The sulfonate ions do not coordinate to metal ion. The cations, non-coordinating sulfonate ions and lattice water molecules are linked by hydrogen bonds to form infinite zigzag chains. CV, FT-IR, UV-Vis and TGA were also used to characterize these compounds. (C) 2003 Elsevier B.V. All rights reserved.
