Abstract

The coordination properties of the macrocycle 1,4,7,10-tetrakis(2,4-dimethyl-1-hydroxy-6-methyl-benzyl)-1,4,7,10-tetraazacyclododecane, H₄L^Me,Me have been investigated with lanthanides La(III) and Pr(III) and _3/4d metal ions Zn(II) and Y(III). Two Pr(III) complexes [Pr(HL^Me,Me)]‧MeOH (2a) and [Pr(HL^Me,Me)]‧2H₂O (2b) with coordination numbers (C.N.) 7 and 8, respectively as well as the [La(HL^Me,Me)]‧2H₂O (1) complex, which was isomorphic with 2b were isolated. In addition, [Y(HL^Me,Me)]‧CH₃CN‧H₂O (3) and [Zn(H₃L^Me,Me)](NO₃) (4) with C.N. 7 and 5, respectively were synthesized too. All complexes were spectroscopically and structurally characterized as well as luminescence emission of 2a and 2b.
