The solvent and the coordination ability of the precursor zinc salt anion control the crystalline products formed by slow diffusion at room temperature: perchlorate allows isolation of the phase pure crystalline 1D polymer [Zn(tph)(L)]·H2O·3DMF}n (1·H2O·3DMF, DMF = N,N-dimethylformamide). In contrast, zinc chloride leads to the formation of either a mixture of polymeric 1·H2O·3DMF and a dimeric molecular
A novel type of tetranuclear cluster with the trinucleating ligand 1,2-Bis(benzimidazol-2-yl)-1-hydroxyethane. Crystal and molecular structure of Ni(HRSL)2(CF3SO3)2 and [Cu4(SL)4(NO3)2(EtOH)] (NO3)2(EtOH)3(H2O)2; spectroscopy and magnetism of these and related transition metal compounds

with CuO distances varying from 2.5 6(2) to 2.93(2) A. Ni(HRSL) 2 (CF 3 SO 3 ) 2 ( II ) crystallizes in the monoclinic space group C 2/ c , with a =21.985(3), b =11.786(2), c =14.816(2) A,β=94.67(1) o , Z =4 (i.e. four HRL units and four HSL units). The nickel(II) ion is octahedrally coordinated by 2 oxygen atoms and 4 nitrogen atoms in a cis geometry. NiN distances are 2.04–2.06 A, whereas NiO 2

1,2‐Bis(benzimidazol‐2‐yl)ethanol (1) and its bis‐N‐methylated derivative (2) act as chiral tridentate facially coordinating ligands capable of binding metals right across the d‐series. Octahedral complexes of divalent and trivalent metal ions are synthesised and characterised by X‐ray crystallography. Only two of the three possible diastereomers are observed in complexes of the type [M(1,2)2] and
Porphyrin metal–organic framework PMOF-2 with a 3D pillar-layered framework showed a better third-order NLO performance than PMOF-1 with a 2D bilayer, revealing the influence of dimensions on third-order nonlinear properties of MOFs.
