Perchlorate and Tetrafluoroborate Complexes of Mn(II), Ni(II), Co(II), and Cu(II) with Tetrabenzo-(b,e,l, o)- 4,14-Dithia-1,7,11,17,-Tetraaza-8,10,18,20-Tetramethyl- cylodedeca-7,10,17,20-Tetraene

Abstract

Eight macrocyclic complexes have been prepared by the template condensation reaction between di(2-aminopenyl) sulphide and acetylacetone. These complexes have the general formula [M(L)]X₂ and [M´(L)(H₂O)₂]X₂ where L ═ tetrabenzo-(b,e,l,o)-4,14-dithia-1,7,11, 17-tetraaza-8,10,18,20-tetramethylcyclodedeca-7,10,17,20-tetraene, M ═ Ni(II), Cu(II); M´ ═ Mn(II), Co(II) and X ═ ClO₄–, BF₄–. The complexes have been characterized on the basis of analytical data, conductance measurements, IR, ¹H NMR, magnetic and electronic spectral studies and are assigned to have either square planar or octahedral geometries.
