Abstract:
In the title complex, [Pt(N(3))(4)(C(10)H(9)N(3))], the Pt(IV) ion is six-coordinated in a slightly distorted octa-hedral environment by the two pyridine N atoms of the chelating di-2-pyridyl-amine (dpa) ligand and four N atoms from four azide anions. The dpa ligand is not planar, the dihedral angle between the pyridine rings being 20.0 (3)°. The azide ligands are slightly bent [N-N-N = 173.5 (8)-175.1 (8)°]. In the crystal, the complex mol-ecules are connected by N-H⋯N hydrogen bonds, forming a chain along the b axis. An inter-molecular π-π inter-action between the chains is also present, the ring centroid-centroid distance being 3.713 (4) Å.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

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...
