Please follow the instructions and answers the questions below using crystalmaker software, 1.

You can also plot planes to look for particular faces or cleavage planes. Please try spinning the images and looking at them from different angles and play with the menus and toolboxes to get familiar with the software. CRYSTALMAKER EXERCISES In addition to answer the questions below, you might find it useful to use crystalmaker to visualize some of the crystal chemistry we have talked about in lecture.

Multi-scan ( CrysAlis PRO Oxford Diffraction, 2006 ) Lastly, the di-iodo carbazole has been used as a ligand in a copper(I) complex as demonstrated by Kim and co-workers (ZASYUQ Kim et al., 2017 ). A derivative of compound I that bears two iodine atoms in the same positions and a hydrogen atom bonded to the nitrogen atom has been solved as structure YAYDUZ (Xie et al., 2012 ).

Structure ECUNUM bears bromine atoms at the C5 and C11 positions with a phenylcarbamate group on the nitrogen atom (Duan et al., 2006 ). The structures CEYXAI (Malecki, 2018 ) and FUMLIK (Radula-Janik et al., 2015 ) are closely related to that of compound I with iodine atoms at the C5 and C11 positions, but where the nitrogen atom has been alkylated with either a butyl or benzyl group. A search of the Cambridge Structure Database (CSD version 5.43 with updates through June 2022 Groom et al., 2016 ) for structures containing the carbazole ring system substituted with any halogen atom at the C5 and C11 positions (as numbered in Fig. 1 ) returned 101 hits.
