چکیده

The pendant-arm macrocycle, meso-5,5,7,12,12,14-hexamethyl-1,4,8,11tetraazacyclotetradecane-1,8-di-(1-methylnaphthalene) has been synthesized and its single crystal structure determined. The molecule crystallizes in a primitive monoclinic cell, with the space group P21/a (#14). The cell dimensions are a = 10.778(3)Å, b = 13.809(3) Å, c = 11.420(2) Å, ∃ = 102.49(2)°, volume = 1659.5(6) Å.

The reactions of Pb(C10 ) , and Pb(SCN) with meso-5,7,7,12,14,14-hexamethyl- 1,4,8,ll ,tetra-azacyclotetradecane (C ,H ,N = L) yielded colorless crystals of LPb(CI O ) (1) and LPb(NCS) (2), respectively. Their structures were determined by X-ray crystallography. Crystal data: 1 monoclinic, P 2 /c, a =11.293 (4) ?, b = 16.382 (6) ? , c = 21.518(4) ?, ? = 92.14(2)?, Z = 4, MoKa, 1824 obser...

The asymmetric unit of the title compound, C30H46N6O4, contains one half-mol-ecule. The C(benzene)-C(CH2)-N-C(-Me) torsion angle is -79.89 (13)° suggesting a synclinal orientation of the nitro-benzene ring with respect to the macrocycle. The conformation of the macrocycle is stabilized by intra-molecular N-H⋯N hydrogen bonds.
