چکیده
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.

In the title compound, [Cu(C(16)H(20)N(2)S(2))(H(2)O)](NO(3))(2)·CH(3)CN, the Cu(II) atom displays a distorted square-pyramidal coordination, in which a water mol-ecule occupies the apical position and the basal plane is formed by two N atoms and two S atoms of a 1,8-bis-(pyridin-2-yl)-3,6-dithia-octane ligand. The crystal packing is stabilized by O-H⋯O and C-H⋯O hydrogen bonds.
