Attempted functionalisation of a mononuclear barium complex of a 24-membered bibracchial tetraimine Schiff-base macrocycle derived from tris(2-aminoethyl)amine using salicylaldehyde

Abstract

Functionalisation of a mononuclear barium Complex of a 24-membered bibracchial tetraimine Schiff-base Macrocycle (L1) derived from the barium-templated cyclocondensation of 2,6-diacetylpyridine and tris(2-aminoethyl)amine was attempted using salicylaldehyde. The reaction leads to the isolation of the tripodal ligand tris[2-(salicylideneamino)ethyl]amine (L2) and the complex BaL22(ClO4)2. The crystal structures of the parent macrocyclic complex, [BaL1][ClO4]2[monoclinic, space group P21/c(no. 14), a= 11.755(7), b= 21.733(17), c= 15.621(15)Å, β= 90.50(7)°, Z= 4], and BaL22(ClO4)2[monoclinic, space group P21/c(C2h5, no. 14), a= 12.299(15), b= 9.530(15), c= 25.798(32)Å, β= 108.679(9)°, Z= 2] have been determined.
