trans-Bis(1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato-κO,O')bis-(4-methyl-1,2,3-selenadiazole-κN)copper(II)
Abstract:
In the title compound, [Cu(C(5)HF(6)O(2))(2)(C(3)H(4)N(2)Se)(2)], the Cu(II) atom (site symmetry ) is coordinated by two O,O'-bidentate 1,1,1,5,5,5-hexa-fluoro-2,4-penta-nedione (hp) ligands and two 4-methyl-1,2,3-selenadiazole mol-ecules, resulting in a slightly distorted trans-CuN(2)O(4) octa-hedral geometry in which the cis angles deviate by less than 3° from 90°. The selenadiazole plane is canted at 73.13 (17)° to the square plane defined by the penta-nedionate O atoms. The F atoms of one of the hp ligands are disordered over two sets of sites in a 0.66 (3):0.34 (3) ratio. There are no significant inter-molecular inter-actions in the crystal.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

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...
