Solvent roles in metal ion coordination: the NiCl2 O-solvates, NiCl2·4MeOH, NiCl2·2MeOH·0.5dioxan and NiCl2·2H2O·2dioxan

Crystal-to-crystal transformation from a chain compound to a layered coordination polymer

“…1, compound 1 consists of neutral chains of CuBr 2 (1,4-dioxane)(H 2 O) 2 and isolated 1,4-dioxane molecules, which is similar to CoBr 2 (1,4-dioxane) 2 (H 2 O) 2 and NiCl 2 (1,4-dioxane) 2 (H 2 O) 2 , different from the obtained 0D compound of CuCl 2 (1,4-dioxane) 2 (H 2 O) 2 . [4][5][6] Within the chain, each Cu 2+ ion is octahedrally coordinated by two Br − (Cu-Br 2.4198( 6 Due to the hydrogen bonds in 1 and the μ-Br bridge in 2, the magnetic properties of these compounds have been studied.…”

13 Iron, cobalt and nickel

“…It includes factors like the effect of acidity, temperature and complexation on particle size and the synthesis of nanocomposites. 10 2 Simple binary and coordination compounds of hydrogen, oxygen, nitrogen and halogen donors 11 There have been a number of further reports, particularly from Gibson and co-workers, studying the use of five coordinate iron(II) complexes as catalysts for ethane polymerisation. Study of some five coordinate bis(imino)pyridine complexes has shown a striking dependence of catalytic ability upon the heteroatom in an apparently remote sidechain.…”
