TL;DR: The compartmental macrocyclic complexes [Ln(H 2 -L)-(N 0 3 )], where H 2 −L is the cyclic Schiff base, have been characterized by ESEM-EDS, ESI-MS, and IR and 1 H and 13 C NMR spectroscopy.
Abstract: The [2+2] compartmental macrocyclic complexes [Ln(H 2 -L)-(N0 3 )], where H 2 -L is the cyclic Schiff base, derived from the condensation of 2,6-diformyl-4-chlorophenol (H-L A ) or 2,6-diformyl-4-methylphenol (H-L B ) and N,N-bis(2-aminoethyl)-2-hydroxybenzylamine·3HCl (HA'·3HCl), contains a free N 3 0 3 coordination chamber and can act as a ligand toward an identical or a different lanthanide(III) ion and a d transition metal(II) ion to give the related f,f homodinuclear [Ln 2 (L)-(X) 2] and f,f' heterodinuclear [LnLn'(L)(X) 2 ] or d,f heterodinuclear [LnM(L)(X)] complexes. They have been characterized by ESEM-EDS, ESI-MS, and IR and 1 H and 13 C NMR spectroscopy. The X-ray single-crystal analysis of the [2+1] acyclic complex [Lu 2 (L') 2 ], derived from partial hydrolysis of the related [2+2] homodinuclear complex [Lu 2 (L)(Cl) 2 ], followed by the loss of one lutetium(III) ion with the free formyl groups turning into diacetal ones, is also reported.
