“…[10] The structure was refined by full-matrix least-squares methods with the SHELX97 program. [11] Owing to the relatively high internal R value, calculated on the equivalent reflections, anisotropic thermal factors were used only for Ni, N and O atoms. The hydrogen atoms were introduced in calculated positions and allowed to ride on the connected heavy atoms.…”

“…The two propyl groups were refined as distributed in two different conformations with a constrained geometry, while the THF molecule was refined with a fixed conformation taken from a well-refined structure in the literature. [11] At the end of the refinement, residual peaks and holes of 0.403 and Ϫ0.339 e·Å Ϫ3 were present around the disordered solvent molecule of the difference Fourier map. The solution and constrained refinement were done by means of the SHELX97 programme.…”

Nickel(II) complexes derived from three new bis‐bidentate Schiff bases, H2L1−3, having two N‐n‐propyl‐salicylaldiminate units linked by an O−(CH2)n−O spacer (n = 4, 8, 12, respectively) at the 3‐position of the salicyl moieties, are described. The pyridine adduct of the complex with the shorter spacer forms a cyclic trinuclear structure, [Ni3(L1)3(py)6] (2), in the solid state, where each NiII ion is octahedrally coordinated by two N,O‐bidentate arms of two different ligands and two pyridine nitrogens. The base with n = 8 leads to the double‐helical dinuclear complex, [Ni2(L2)2]·THF (3), which is the first example of a structurally characterised helicate based on a square‐planar N2O2 coordination geometry. In CHCl3 solution, 3 undergoes a disassembly process which results in an equilibrium mixture where the mononuclear species is largely predominant.

The pentafluorosulfanyl group (SF5) is a highly stable chemical function which has been attracting a great deal of interest owing to its peculiar chemical, structural, physicochemical and biological properties. Progress in the area of SF5-compounds has been somewhat hindered by the lack of straightforward lab-scale synthetic methods for introducing the SF5-group into organic molecules. However, recent synthetic progress, the availability of some SF5-building blocks from commercial suppliers and the discovery of interesting properties of SF5-substituted molecules in materials science, biology and drug discovery are giving new momentum to research in this fascinating area of fluorine chemistry. Synthesis, reactivity and biological properties of SF5-substituted organic molecules are herein reviewed with an emphasis on the work published after year 2000. Object *Cover Letter or Page containing Author DetailsAll of the referees' suggestions have been accepted, with the only exception of Referee's 2 point 5 "Reactions of ArylSF5 systems should be divided into sections …electrophilc substitutions, nucleophilic substitutions, reactions of diazo systems,…" because in that section the chemistry is inherently heterogeneous and we feel that such a subclassification would be very challenging to achieve and would make less homogeneous the discussion of the topic. Molecolare, via Mancinelli 7, 20131 Milano, Italy Synthesis, reactivity and biological properties of SF 5 -substituted organic molecules are reviewed in this article, with an emphasis on the work published in the last decade. *Graphical Abstract -Synopsis Highlights We review the synthesis of SF 5 -compounds, with an emphasis on work published after year 2000.  We review the reactivity of SF 5 -substituted organic molecules.  We review the biological properties of SF 5 -substituted drug candidates.
