CR(III), FE(III), CO(II), CU(II), AND ZN(II) COMPLEXES WITH 3,3-DIMETHYL-1-N-(1-PHENYL-2,3-DIMETHYL-5-OXO-3-PYRAZOLIN-4-YL)IMINO-1,2,3,4-TET RAHYDROIS OQUINOLINE

摘要
The interaction of Co(II), Cu(II), Zn(II), Cr(III), and Fe(III) salts with 3,3-dimethyl-1-N-(1-phenyl-2,3-dimethyl-5-oxo-3-pyrazolin-4-yl)imino-1,2,3,4-tetrahydroisoquinoline (L) (acetone, 25 degrees C, M : L = 1 : 1) gives three types of complexes [(HL)MX(3)] center dot ac (M = Cu(II), Zn(II); X = Cl(-), Br(-); ac is a solvate acetone molecule; HL is a cation formed by protonation of the exocyclic N atom of L), ML(2)Y(2) center dot nH(2)O (M = Co(II), CU(II); Y = NO(3)(-), ClO(4)(-); n = 1, 2), and MLCl(3) center dot 5H(2)O (M = Cr(III), Fe(III)). The composition of the complexes is confirmed by the results of elemental analysis and measurements of the refractive index. On the basis of X-ray diffraction data for the previously studied complex [(HL)CoCl(3)] center dot ac and the IR and electronic absorption spectra, the coordination mode of L in the synthesized complexes is considered.
