Abstract
In this study we focus on the coordination chemistry of a family of three flexible benzotriazole-based ligands (L1–L3) using cobalt(II) salts. Our efforts have resulted in the formation of 10 novel compounds, formulated as [Co2(L1)2Cl4]·2MeCN (1·2MeCN), Co2(L1)2Br4 (2), [Co(L2)Cl2]·MeCN (3·MeCN), Co(L2)Cl2 (4), [Co2(L2)2Br4]·2MeCN (5·2MeCN), [Co(L2)2(NO3)2]·2MeCN (6·2MeCN), [Co2(L3)2Cl4]·2MeCN (7·2MeCN), Co2(L3)2Cl4 (8), Co2(L3)2Br4 (9), and Co(L3)2(NO3)2 (10). The structures have been well characterized through X-ray crystallography, Fourier transform-infrared spectroscopy, electrospray ionization mass spectrometry, powder X-ray diffraction, elemental analysis, and thermogravimetric analysis studies. The compounds show a large structural variety depending on synthetic parameters (ratio, temperature, and metal salt) and the ligand selection (various conformations in each ligand). When tuned appropriately, these factors drastically affect dimensionality, metal geometry, and the nuclearity of the final prod...
