摘要
2,6-二甲酰对甲苯酚和三(2-氨乙基)胺在硝酸铈的模板作用下缩合得到单核穴状Schiff碱配合物[CeNO3·L](NO3)2,铈为九配位。配合物的晶体属三斜晶系,P1↑-空间群,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)nm^3,Z=2。
A mononuclear 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= N bonds 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.
