By convention, the edge of a unit cell always connects equivalent points. Each corner of the unit cell is defined by a lattice point at which an atom, ion, or molecule can be found in the crystal. Again, the unit cell is shown with blue dashed lines and the color scheme is the same as the above images. You have crystal structure data (either space group/unit cell/atomic parameters or a file (e.g. Note that the maximum bond distances printed in this file correspond to the maximum value in the Transform > List Bonds sheet/dialog. The simple cubic unit cell is the simplest repeating unit in a simple cubic structure. Using the Bond Distance or Bond Angle tools.ĭetailed output is printed, with errors in the Log pane of the Overview window.Ĭreating a Bonds file, using: File > Export Data > Distances & Angles.Īn output file is created, containing detailed information about bond distances and angles, with their errors. You can then read the text file into CrystalMaker, using the File > Open command. ! Note the new "errors" line: The syntax is: The generated surface is aligned in the XY plane, and a specified thickness will be cleaved in the z-axis below the XY plane. XYZR 0.9000 2.1000 0.9000 2.1000 0.9000 2.1000 Specify the indices of the Miller plane desired (for hexagonal unit cells, all 4 indices will appear), and choose the dimensions in either distances or repeating cells of the resulting surface. ! they're probably bigger than the true errors! ! cell parameters I've guessed these errors. ! NOTE the "ERRC" card: errors in the unit str file extension - which is also claimed by a number of other programs including ATOMS and STRUPLO (also read by CrystalMaker).

Crystal Structure Images Generated Using CrystalMaker: A Crystal and Molecular Structures Program for Mac and Windows. (C) the color of corundum is determined by the proportions of the trace elements. Note that TOPAS structure files use the generic. (A) The unit cell of corundum viewed down the z axis, (B) the unit cell viewed down the x axis.

This is a test to demonstrate error propagation. CrystalMaker can read the full spacegroup, unit cell and asymmetric unit (including occupancies and optional isotropic or anisotropic displacement parameters).
