Metal Tropocoronand Complexes

Submitted by Anthony L. Fernandez / Merrimack College on Wed, 01/17/2018 - 13:36
Description

This exercise looks at the metal complexes of tropocoronand ligands, which were first studied by Nakanishi, Lippard, and coworkers in the 1980s. The size of the metal binding cavity in these macrocyclic ligands can be varied by changing the number of atoms in the linker chains between the aminotroponeimine rings, similar to crown ethers. These tetradentate ligands bind a number of +2 metal centers (Cd, Co, Cu, Ni, and Zn) and the geometry of the donor atoms around the metal center changes with the number of atoms in the linker chains.

Inorganic Chemistry I with Laboratory

Submitted by Chip Nataro / Lafayette College on Mon, 01/15/2018 - 12:17
Description

Introduces the theories of atomic structure and bonding in main-group and solid-state compounds. Common techniques for characterizing inorganic compounds such as NMR, IR, and mass spectrometry are discussed. Descriptive chemistry of main group elements is examined. Conductivity, magnetism, superconductivity, and an introduction to bioinorganic chemistry are additional topics in the course. In lieu of the laboratory, students have a project on a topic of their choice. Serves as an advanced chemistry elective for biochemistry majors.

Geometry Indices

Submitted by Anthony L. Fernandez / Merrimack College on Fri, 01/12/2018 - 23:20
Description

In the primary literature, goemetry indices are being used quite often to describe four- and five-coordinate structures adopted by transition metal complexes. This slide deck, which is longer than the intended 5 slides, describes the three common geometry indices (tau4, tau4', and tau5) and provides example calculations for structures that are freely available in the Teaching Subset of the Cambridge Structural Database. (Students can access these structures in Mercury, which is freely available from the CCDC, or via a web request form for which the link is provided below.)

Visual scaffold for stoichiometry

Submitted by Margaret Scheuermann / Western Washington University on Tue, 12/19/2017 - 22:18
Description

These five slides are intended to share a visual scaffolding that I developed to help my general chemistry students identify what calculations are needed to solve stoichiometry problems.
