Abstract:
In the title complex, [CuTb(C(19)H(20)N(2)O(4))(NO(3))(3)]·CH(3)COCH(3), the Cu(II) atom is four-coordinated by two O atoms and two N atoms from the deprotonated Schiff base in a square-planar geometry, while the Tb(III) atom is ten-coordin-ated by four O atoms from the deprotonated Schiff base and six O atoms from three bidentate nitrate anions. The compound is isostructural with the previously reported Gd(III) analogue [Elmali & Elerman (2004 ▶). Z. Naturforsch. Teil B, 59, 535-540], which was described in the space group P1 with two formula units in the asymmetric unit. The crystal stucture is, in fact, centrosymmetric and is described here in the space group P with one formula unit in the asymmetric unit.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
