Abstract:
The Pt(II) ion in the title complex, [PtCl(2)(C(14)H(10)N(4))], is four-coordinated in a distorted square-planar environment by two N atoms of a chelating 2,3-di-2-pyridyl-pyrazine ligand and two chloride anions. The pyridyl ring coordinated to the Pt(II) atom is inclined slightly to its carrier pyrazine ring [dihedral angle = 13.5 (1)°], whereas the uncoordinated pyridyl ring is inclined considerably to the pyrazine ring [dihedral angle = 54.3 (2)°]. The dihedral angle between the two pyridyl rings is 59.2 (2)°. In the crystal, the complexes are assembled through inter-molecular C-H⋯N and C-H⋯Cl hydrogen bonds, forming a three-dimensional network. Intra-molecular C-H⋯N and C-H⋯Cl hydrogen bonds are also present.

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,...
