Tris(nitrato-κO,O')bis-(1,10-phenanthroline-κN,N')holmium(III)
Abstract:
In the title compound, [Ho(NO(3))(3)(C(12)H(8)N(2))(2)], the ten-coordinate Ho(III) ion is chelated by four N atoms from two phenanthroline (phen) ligands and six O atoms from three bidentate nitrate groups. The environment around the Ho atom can be described as a distorted bicapped square anti-prism. Two phenanthroline ligands form a dihedral angle of 43.72 (13)°. Short inter-molecular distances between the centroids of the six-membered rings [3.6887 (14)-3.8374 (16) Å] indicate the existence of π-π inter-actions, which link the mol-ecules into stacks extended in the [10] direction. The crystal packing is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

Coordination Compounds and Nomenclature
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...

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...
