Abstract: New macrocyclic squares of the type  [(bisphos)M(BIX)]2 (BF)4.n CHCl3 where M=Ni(II), Pd(II) and Pt(II) have been synthesized using nonchelating ligands, viz., 1,3- and 1,4-(benzimidazole-1-yl- methylene)benzene (hereafter 1,3- and 1,4-BIX) and [(bisphos)M(CH3OH)2(BF4)2] {for M=Ni(II) and Pd(II), bisphos = diphenylphosphinopropane (dppp); for M = Pt(II), bisphos=diphenyl phosphinoethane (dppe)}. These complexes have been characterised using C, H, N analyses, IR, UV-VIS, 13C-NMR and FAB-mass studies. CPK model (Corey-Pauling-Koltun) of these macrocycles indicates that the cavity size is suitable for inclusion of benzene substituted guests.
