Synthesis and Crystal Structure of Cerium Complex of Schiff Base Cryptand

Abstract

Abstract: Amononuclear cerium complex [CeNO₃·L] (NO₃)₂ of hexaimino cryptand was obtained by condensation of tris (2-aminoethyl) amine with 2, 6-diformyl-4-methyl phenol in the template procedure.The complex is nine-coordinate with five oxygen atoms from three phenols and a bidentate nitrate, and four nitrogen atoms from three imino C= Nbonds and a tertiary amine in the cryptand.The complex crystallized in triclinic system, space group P1, a=1.0833(3) nm, b=1.2654(4) nm, c=1.7626(7) nm, α=83.48°(3), β=89.28 (3)°, γ=83.70(3)°, V=2.386(2) nm³, Z=2.
