A dinuclear copper salicylate [Cu2(HSal)(Sal)(2,2′-bpy)2](ClO4) (1) (H2Sal = salicylic acid) has been synthesized and characterized with the aid of elemental analysis and infrared, ultraviolet and fluorescence spectroscopic studies. The molecular structure of 1, determined by single-crystal X-ray diffraction studies, shows the presence of incompletely deprotonated salicylate ligands in the complex. Hydrogen bonding interactions and π-π aromatic stacking lead to the formation of 2D polymeric structure in the solid state. © 2006 Elsevier B.V. All rights reserved.

A novel dimeric copper salicylate with an undissociated COOH group: Synthesis and crystal structure of [Cu2(HSal)(Sal)(2,2′-bpy)2](ClO4)

Aminosilanes bearing bulky substituents on nitrogen centers, [(ArNH)2SiPh2] (Ar=2,6-iPr2C6H3 (1), 2,4,6-Me3C6H2 (2), 2,6-Et2C6H3 (3)), have been prepared in good yields by the addition of dichlorodiphenylsilane to the corresponding substituted monolithiated aniline. The new compounds have been characterized by elemental analysis and IR, EI mass and NMR (1H and 29Si) spectroscopic studies. The solid-state structures of 1 and 3 have been determined by single crystal X-ray diffraction studies. The molecules have a Cs symmetry and the two N-H protons are approximately trans to each other. The amido nitrogen atoms show significant deviation from trigonal-planar geometry, as a result of which the observed Si-N bonds are marginally longer than those observed in aminosilanes with planar nitrogen atoms. © 2003 Elsevier Science B.V.
