Solvent roles in metal ion coordination: the NiCl2 O-solvates, NiCl2·4MeOH, NiCl2·2MeOH·0.5dioxan and NiCl2·2H2O·2dioxan
摘要:
Low-temperature, single crystal X-ray structural characterisations of trans-[NiCl2(HOMe)(4)], trans-O-[Ni(MeOH)(2)-(mu-Cl)((2/2)2)]((x, x))(.)0.5dioxan and trans-trans-[Ni(H2O)(2)Cl-2(O-dioxan-O)((2/2))]((x,x))(.) dioxan are recorded, offering intriguing insights into O-donor/Ni(II) relativities. All nickel atoms in all structures are located on crystallographic inversion centres, the last two compounds being one-dimensional polymers. (C) 2004 Elsevier B.V. All rights reserved.
