- Chemical Design is pleased to announce some exciting new developments in
- the handling of inorganic structures by Chem-X, including enhanced
- molecular mechanics for organometallic structures. Significant
- improvements have been made to the modeling of pi-bonded systems, such as
- aromatic rings connected to a metal atom. Chem-X is now able to handle a
- wide range of coordination states and bond angles found in organometallic
- systems.
-
- Chem-X's molecular mechanics force-field includes parameters for bond,
- angle, torsion and non-bonded interactions. In addition to parameters
- supplied, users may modify Chem-X molecular mechanics parameters using
- Chem-X commands. Enhancements to parameterization mean that correct bond
- angle terms are automatically included and there is provision for a given
- bond order to lead to more than one bond length term - e.g. for axial vs.
- equatorial bonds (important for modeling Jahn-Teller effects).
-
- The pi-bonding model makes use of the concept of dummy atoms, already
- present within Chem-X. The dummy atom is placed at the center of the
- pi-bonded system, e.g. an aromatic ring, and bonded to the central metal
- atom. The use of the dummy-metal bond allows the pi-bonded ring to rotate
- about the bond axis.
-
- Chemical Design is the leading supplier of molecular modeling systems, with
- over 350 installations of its Chem-X software worldwide. Chem-X is used
- for new product research in areas as diverse as pharmaceuticals,
- agrochemicals, petrochemicals, polymers and protein engineering. Customers
- include divisions of most major multinational chemical and pharmaceutical
- companies as well as many leading academic research centers. Chem-X is
- available for PC, Apple Mac, UNIX workstation and VAX computers.
