Commission on
Nomenclature of Inorganic Chemistry (II.2)
Summary of Minutes
of Commission Meeting at IUPAC General Assembly, Berlin, Germany, 9-11
August 1999
Commission II.2 (CNIC) reviewed two documents that
had been completed in August of 1998 but were found not ready at that
time for forwarding to Pure and Applied Chemistry. There were
some questions concerning the use of "ido" and "ato" in the inorganic
radical document by Prof. Wim Koppenol. These matters were resolved
and Prof. Koppenol will modify the document to remove inconsistencies.
The document by Prof. Koppenol concerning the naming of elements 110
and higher was brought into conformance with the one presented to the
Commission in August 1998 by Prof. John Corish, Prof. G. J. Leigh, and
Dr. Gerd Rosenblatt. The Commission agreed unanimously that, to avoid
confusion in the literature and electronic searching, if a name has
been used unofficially for an element and that name is not accepted
as the official IUPAC name, then it should not be proposed for another
element at a future date.
The publication date for Red Book II will depend upon
how quickly arrangements are concluded with a publisher. A document
on muon nomenclature, also by Prof. Koppenol, was revisited and, with
minor revisions, was approved to go forward. It will be submitted to
Commission V.7 (Radiochemistry and Nuclear Techniques) for comment before
proceeding. The organometallic paper by Prof. Albrecht Salzer will be
submitted to PAC after IDCNS review.
The revision of Red Book I continues under the direction
of Prof. Neil Connelly. This revision will include the chapter on ligand
abbreviations, errors will be removed, and the nomenclature will be
made consistent for all chapters. A separate project was proposed and
accepted for this update of Red Book I under the new IUPAC project-managed
system. A progress report on computer-assisted nomenclature was presented,
and it showed that it is possible to generate a number of unique structures
for convex polyhedra. However, it was noted that purely mathematical
solutions were unsatisfactory unless parameters were added to eliminate
chemically improbable solutions. A joint meeting was held with the Commission
on Nomenclature of Organic Chemistry (CNOC) to discuss common areas
of concern. Members of both Commissions involved in computer-assisted
nomenclature will meet to discuss common goals. At the joint meeting,
it was agreed to continue a collaborative effort to produce a book on
organometallic nomenclature. CNOC will work on main group elements,
and CNIC will work on transition metals (Prof. Salzerís document
and metallacycles). Additionally, other chapters will be solicited.
These two efforts, computer-assisted nomenclature and organometallic
nomenclature, are expected to develop into separate projects under the
project-funded system. A metallacyclic paper by Prof. Yohsuke Yamamoto
was discussed, and further revisions will be made and circulated to
the Commission members before the next meeting. The Commission will
meet again in August 2000 in Dublin, Ireland.
