As a class of compounds, the metallophthalocyanines exhibit a wide array of physical and chemical properties that can be profoundly affected by subtle changes in their structures. Shown here is methanol(h4-phthalocyaninato) magnesium(II), a recent addition to the list of compounds that fit this classification. This compound adopts a crystal structure that results from two different types of interactions between molecules. These are known as p-p dimerization and hydrogen bonding. One interesting subtlety in the structure of the molecule shown can be described as a "hat visor" shape, a description put forth for the first time in a very recent paper describing this structure. This molecule is only one of several related compounds under investigation through a collaboration involving Dr. Ilia Guzei, Director of the Molecular Structure Laboratory at the University of Wisconsin-Madison and Robert McGaff, an Associate Professor of Chemistry at the University of Wisconsin-La Crosse.
Welcome to Reciprocal Net

The Reciprocal Net is a distributed database used by research crystallographers to store information about molecular structures; much of the data is available to the general public. The Reciprocal Net project is still under development. Currently, we have 18 participating crystallography laboratories online. The project is funded by the National Science Foundation (NSF) and part of the National Science Digital Library. More about Reciprocal Net.
