Reactions of [BiBr6]3− and bromide salts of various substituted pyridinium cations in excess of HBr result in a series of bromobismuthate anionic complexes of various geometry and nuclearity: [{BiBr4}n]n−, [Bi2Br9]3− and [Bi2Br10]4−. Hirshfeld surface analysis for 19 crystal structure was performed; impact of various X-Br contacts on the crystal structures is discussed.
Reactions of the Schiff base ligand OH-C6H4-CHNC(CH2OH)3 (H4L) with copper(II) salts in various reaction media afforded complexes [Cu4(H2L)4]·MeOH (1·MeOH), [Cu2(O2CMe)2(H3L)2] (2), [Cu4(H2L)4(H2O)2]·1.5dmf (3·1.5dmf), [Cu4(H2L)4(H2O)]·MeOH (4·MeOH) and [Cu4(H2L)4]2·2H2O·7MeOH (5·2H2O·7MeOH). Compounds 1, 3 and 4 consist of neutral tetranuclear entities in which the CuII ions are coordinated by the...
