title: {1,8-Bis[2-(2-oxidobenzyl-idene-amino)phen-oxy]-3,6-dioxaocta-ne}nitrato-praseodymium(III) trichloro-methane solvate.
abstract: In the title compound, [Pr(C(32)H(30)N(2)O(6))(NO(3))]·CHCl(3), the Pr(III) ion is ten-coordinated by eight O atoms and two N atoms from the acyclic crown-type Schiff base ligand and the bidentate nitrate group. The coordination polyhedron around Pr(III) is a distorted bicapped square anti-prism. The chloro-form solvent mol-ecule is not involved either in coordination to the Pr(III) center or in hydrogen bonding to the complex. The Pr-O(phenolate) bonds are significantly shorter than the Pr-O(ether) and Pr-O(nitrate) bonds, which suggests that the Pr-O(phenolate) bond is stronger than these other bonds. In the crystal structure, the acyclic crown-type Schiff base ligand wraps around the Pr(III) centre, forming a pseudo-ring.
