N-Substituted lariat crown ethers N,N'-bis(3- Two new hydroxy-6-methyl-pyridinemethy1)-1, 10-diaza-4, 7, 13, 16-tetra- oxacyclooctadecane (L) and N, N-bis(8-quinoline-methyl)-1,10- diaza-4,7,13, 16-tetraoxacyclooctadecane (L2) were synthesized. Their crystal structures were determined by X-ray diffraction method. The single crystal of L1(C26H40N406) belongs to triclinic, space group P1 with a=9.239(2)A, b=11.273(2)A.c=7. 1150(10)A, a=91.86(3)0, B=110.47(3)9, y=99.11(3)8, V=682. 4(2) A", Mr=504.62, Z=1,Dc=1.228Mg/m3,μ=0.088mm-1+,F(000)=272.reflections,R=0.0380, wR=0.1118.
