  1. Advanced Inorganic Chemistry Chemistry 470 Br. Manner

  2. What is Inorganic Chemistry? • The chemistry of “everything else” • Chemistry of coordination compounds • [Mo2Cl8]4-; Mo2(O2CCH3)4; [Co(en)3]3+; and [Cr(H2O)6]2+ • Chemistry of organometallic compounds • Fe(C5H5)2and [PtCl3C2H4]-1 • Chemistry of bioinorganic materials • Vitamin B12 and hemoglobin • Chemistry of materials • Kaolinite; montmorillonite, zeolite, and polyoxometalates And there is even more!!

  3. Bonding in Inorganic Compounds • Type of bonding encountered in inorganic chemistry • Metals can bond to virtually anything • Includes metal-metal bonding (shown previously) • , , and  bonding in compounds and ions • [Mo2Cl8]4- • Coordination number commonly exceeds four • Octahedral environment is very common • SF6

  4. Formation of the Elements (the Big Bang) • Questions from the scientific world. • Scriptural account of the creation. • Big Bang Theory • Journal of Chemical Education (read these) • 1973, 50, 306 • 1973, 50, 380 • Curve of cosmic abundance of the elements. • The stability of Fe-56. Prove that it is more stable than Ti-48. • Use Einstein’s theory of relativity. • Why the difference between even and odd Z elements?

  5. The Detectable Elements

  6. Subatomic Particles Involved in the Formation of the Elements All of these particles are involved with the existence or formation of the elements.

  7. What’s Out There? Is There Enough Matter for the Formation of New Galaxies? • The universe consists of mostly empty space and energy. Relatively, there is very little mass. • Matter consists of normal matter and dark matter (discussed later) • The estimated density of the universe is 5 atoms/m3 • 2  10-28% of the universe’s volume is occupied by matter • There is still enough mass in the universes to form many new planets and galaxies (especially since there is no end). • No need to worry

  10. Even More Matter • Scientists believe that most of the universe is made up of ‘dark matter’. • Dark matter is non-luminous matter, that cannot be directly detected by observing any form of electromagnetic radiation (light), but whose existence is suggested because of the effects of its gravity on the rotation rate of galaxies and the presence of clusters of galaxies. It is believed that neutrinos count for a large portion of this dark matter. • Only a small portion of the mass is ‘normal’ matter (probably <10%). The rest is dark matter. http://www.astronomytoday.com/cosmology/darkmatter.html

  11. Inorganic Chemistry • History of inorganic chemistry (pages 11-14). • Use of molecular orbital theory, symmetry, and group theory will be a common thread throughout this course. • 6-benzenetricarbonylchromium • (6-C6H6)Cr(CO)3 If needed and when encountered, use the recommended texts and reviews to bring you up to speed on these subjects.
