36. Crystal Field Theory

38. Example – Coordination Chemistry • Compare the strong field case of hexaamminecobalt(III) ion to the weak field case of hexafluorocobaltate(III) ion. • What is the oxidation state of each cobalt? • What do the orbital diagrams look like? • Are they high spin, low spin or neither? • What are the hybridized orbitals?

39. Example – Coordination Chemistry • The hexacyanoferrate(III) ion is known to have one unpaired electron. Does the cyanide ion produce a strong or weak field?

40. Example – Coordination Chemistry • Predict the number of unpaired electrons in the complex ion hexacyanochromate(II).

41. Example – Coordination Chemistry • The complex ion hexaaquatitanium(III) absorbs light of wavelength 510 nm and has a reddish-violet color. What is the ligand field splitting in the complex?

42. Crystal Field TheoryTetrahedral and Square Planar Complexes

43. Example – Coordination Chemistry • One method for refining cobalt involves the formation of the complex ion tetrachlorocobaltate(II). This anion is tetrahedral. Is this complex paramagnetic or diamagnetic?

44. Example – Coordination Chemistry • Why is it that the tetracyanonickelate(II) ion is diamagnetic, but the tetrachloronickelate(II) ion is paramagnetic?
