Amine, Amido, and Imido Complexes of Tantalum Supported by a Pyridine-Linked Bis(phenolate) Pincer Ligand: Ta−N π-Bonding Influences Pincer Ligand Geometry [PDF]

open access: yes, 2009
A series of tantalum imido and amido complexes supported by a pyridine-linked bis(phenolate) ligand has been synthesized. Characterization of these complexes via X-ray crystallography reveals both C_s and C_2 binding modes of the bis(phenolate)pyridine ...

Self-Assembly of Supramolecules Consisting of Octyl Gallate Hydrogen Bonded to Polyisoprene-block-poly(vinylpyridine) Diblock Copolymers [PDF]

open access: yes, 2004
Synchrotron radiation was used to investigate the self-assembly in two comb-shaped supramolecules systems consisting of octyl gallate (OG), i.e., 1-octyl-3,4,5-trihydroxybenzoate, hydrogen bonded to the pyridine groups of polyisoprene-block-poly ...

4-(Methylamino)pyridine [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2010
The non-H atoms of the title compound, C(6)H(8)N(2), lie in a common plane (r.m.s. deviation = 0.034 Å). In the crystal, adjacent mol-ecules are linked by inter-molecular N-H⋯N hydrogen bonds into a zigzag chain running along the c axis.
