Abstract:
The Pt(IV) ion in the title complex, [PtBr(4)(C(10)H(9)N(3))], is six-coordinated in a slightly distorted octa-hedral environment by two pyridine N atoms from a chelating di-2-pyridyl-amine (dpa) ligand and four Br(-) anions. The complex mol-ecule has mirror symmetry, with the Pt(IV) atom, two Br atoms and the central N atom of the dpa ligand lying on the mirror plane. The dpa ligand is not planar, showing a dihedral angle of 34.7 (2)° between the pyridine rings. The complex mol-ecules are connected by inter-molecular N-H⋯Br hydrogen bonds, forming chains along [001]. Inter-molecular C-H⋯Br hydrogen bonds and π-π inter-actions between the pyridine rings [centroid-centroid distance = 3.667 (4) Å] are also observed.

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...

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,...
