Abstract
Two crystalline adducts of triethylenediamine with hydroquinone [N(CH2CH2)3N·C6H4(OH)2,I] and phenol [N(CH2CH2)3N·2C6H5OH,II] have been isolated and characterized by X-ray analysis. ComplexI crystallizes in the monoclinic space groupC2/c, witha=11.944(2),b=9.491(2),c=11.986(2) A,β=121.70(1)°, andZ=4. Both molecular components occupy sites of symmetry 2, and are linked alternately by N ⋯ H-O hydrogen bonds to form infinite zigzag chains. Crystals ofII are also monoclinic, with space groupP21/c,a=12.987(2),b=6.376(1),c=21.350(3) A,β=106.94(1)°, andZ=4. The structure is composed of discrete hydrogen-bonded molecular aggregates corresponding to the stoichiometric formula. The triethylenediamine moieties in both adducts closely approximate to the idealizedD3h conformation. The structures have been refined toR values of 0.097 (I) and 0.092 (II) using, respectively, 479 and 1580 observed MoKα data.
