The potentially terdentate NN'N donor ligand 2,6-bis[di-(n-butyl)aminomethyl]pyridine (1) does not form a stable, isolable Ru complex using any standard Ru starting materials. This is in contrast to the dimethylamino derivative 2. In the presence of Zn metal as a reducing agent, the treatment of hydrated ruthenium trichloride with 2 leads instead to the isolation of a diamagnetic Zn(II) complex (3) of general formula [ZnCl2(1)]. Analysis of 3 (NMR, X-ray) reveals the complex to be a mononuclear Zn halide compound containing ligand 1 in an η3-NN'N bonding motif. The Zn atom is found to be five-coordinate and in a geometry best described as midway between trigonal bipyramidal and square pyramidal in structure. Similar experiments using 2 produce an analogous Zn species (4) which has likewise been fully characterized (NMR, X-ray) and found to be similar to 3 although the metal is in a distinctly square pyramidal environment. These compounds are viewed as relatives of the class of Zn "pybox" catalysts.Key words: pincer complexes, zinc(II) compounds, X-ray crystal structure.

The synthesis and characterization of three metalla-rectangles of the general formula [Ru4(η6-p-cymene)4(μ4-clip)2(μ2-Lanthr)2][CF3SO3]4 (Lanthr: 9,10-bis(3,3’-ethynylpyridyl) anthracene; clip = oxa: oxalato; dobq: 2,5-dioxido-1,4-benzoquinonato; donq: 5,8-dioxido-1,4-naphthoquinonato) are presented. The molecular structure of the metalla-rectangle [Ru4(η6-p-cymene)4(μ4-oxa)2(μ2-Lanthr)2]4+ has been confirmed by the single-crystal X-ray structure analysis of [Ru4(η6-p-cymene)4(μ4-oxa)2(μ2-Lanthr)2][CF3SO3]4 · 4 acetone (A2 · 4 acetone), thus showing the anthracene moieties to be available for reaction with oxygen. While the formation of the endoperoxide form of Lanthr was observed in solution upon white light irradiation, the same reaction does not occur when Lanthr is part of the metalla-assemblies.

The synthesis of RbHCN2 was carried out by reaction of cyanamide with rubidium amide in liquid ammonia. The crystal structure has been determinedo by x-ray powder methods (orthorhombic, P21,21,21, a = 7.299(1), b = 9.435(1), c = 9.420(1) Å; Z = 8). The anion is slightly bent (174°) and exhibits two different bond lengths (C-N: 1.17, HN-C: 1.31 Å).
