Source of material
The compound was obtained commercially (Aldrich). Crystals suitable for the diffraction studies were taken directly from the provided product.
Experimental details
Carbon-bound H atoms were placed in calculated positions (C–H 0.95 Å for aromatic carbon atoms, C–H 0.99 Å for methylene groups) and were included in the refinement in the riding model approximation, with U(H) set to 1.2 Ueq(C).
Comment
Chelate ligands have found widespread use in coordination chemistry due to the increased stability of coordination compounds they can form in comparison to monodentate ligands. The stability of these compounds is enhanced further if the denticity of the ligand is increased upon incorporation of more potential donor sites [7]. While cyclic systems (such as crown ethers, cryptands, sarcophaginates and sepulchrates) additionally benefit from the macrocyclic effect and give rise to the formation of some of the most stable coordination compounds known to mankind, a different picture is at hand for open-chain type ligands where, also factors such as pH values in case of deprotonable functional groups come into play. This is for instance the case for EDTA, whose importance in complexometric titrations is well established already in fundamental laboratory courses for undergraduate students. Much less data are at hand for ligands that derive their multidenticity strictly from sigma donor, electrically neutral sites. At the onset of a study aimed at deriving the rules guiding the principles of complexation tendencies for such ligands, the title compound was seen as a tempting starting compound. To allow for the comparison of metrical parameters in the free ligand as well as envisioned coordination compounds of a series of transition metals, rare earth metals, actinides and elements from the main groups, the crystal structure of the free ligand was determined. Similar compounds featuring nitrogen atoms next to keto or thioketo groups have been characterized in the solid state already [8], [9], [10], [11].
The title compound is a derivative of nicotinic amide. The nitrogen atom of the amide group features a benzyl group as well as a nicotinoyl moiety instead of its two hydrogen atoms as bonding partners. The C–O bond lengths are almost identical in length with values of 1.213(2) Å and 1.214(2)Å, and do not show signs of pronounced amide-type resonance stabilization as the pertaining elongation of the C=O bonds is only found at the shorter end compared to other tertiary acid amides as found in the Cambridge Structural Database [12]. The least-squares planes defined by the non-hydrogen atoms of the three aromatic moieties enclose angles of 25.61(11)°, 48.64(6)° and 66.94(6)°, with the smallest and the largest angle of intersection found for the two heterocyclic systems towards the phenyl ring.
In the crystal, C–H…O contacts whose range falls by more than 0.1 Å below the sum of van-der-Waals radii are present. One such contact is established between the hydrogen atom in ortho-position with respect to the intracyclic pnicogen atom N11 and to C11. In terms of graph-set analysis [13], [14], the descriptor for these contacts is
