Now you need to add the axial oxygen atom to the chromium center (if the periodic table window disappeared, click again on the element fragment button on the toolbar). Currently the model should look like the one presented on the picture: Clicking on the equatorial hydrogen atoms in the Molgroup window, change those to the chlorine atoms. From the possible selections at the bottom of the periodic table, choose the chlorine atom with the single bond. In the next step, you need to add the equatorial chlorine atoms to the chromium center (if the periodic table window disappeared, click again on the element fragment button on the toolbar). Click on the Molgroup window (blue window with nothing in it) and the coordination polyhedron you have selected will appear there along with attached hydrogen atoms:
Unfortunately, there is no way to directly choose tetragonal pyramidal coordination for the metal in GaussView yet, so choose octahedral coordination. As a result, you will see the different coordination polyhedrons available for the chromium atom in GaussView at the bottom of the Periodic Table. Click on the chromium symbol in the periodic table. This will open another window with the periodic table in it. Click on the element fragment button on the toolbar, which is located just above the current picture in the gray window.
#Construct zmatrix for gaussian windows
The following GaussView windows should appear:įirst, you will build a simple diamagnetic transition-meal complex, 2. Start the GaussView program by clicking on the GaussView icon from start menu. Make sure you have a laboratory notebook ready to document the progress of this lab. You also can generate an initial coordinates file using HyperChem or other available program by saving those in Brookhaven PDB, MDL, Sybyl Mol2, or CIF formats. You will use the graphical interface developed by Gaussian Inc. In this lab you will make your first Gaussian03W calculation on a small transition-metal complex.

#Construct zmatrix for gaussian how to
In the first lab, you will learn how to do the following:Ĭonstruct an input file using Gaussian03W or text editor It combines a variety of computational methods, including Density Functional Theory, Hartree-Fock as well as correlated or post-Hartree-Fock, Semi-empirical, and Molecular Mechanics approaches. UV-Vis, NMR, IR, EPR, Mossbauer, CD, etc.). Gaussian03W is a computational chemistry program, which can calculate energies, a variety of molecular properties, optimize molecular geometries, and predict spectroscopic properties of the system ( i.e. Single point calculation and visualization Lab : Single Point Lab Gaussian and GaussView Computation and Visualization Notes Page
