Özet

Phosphaza-lariat ethers, which are known as 2,2-[4,4'-(2,2'-oxybis(ethane-2,1-diyl)bis(oxy))dianilino]-4,4,6,6-tetrachlorocyclo-2 lambda(5),4 lambda(5),6 lambda(5-)triphosphazatriene(spiro) (1), 2,2-[4,4'-(2,2'-(ethane-1,2-diylbis(oxy))bis(ethane-2,1-diyl))bis(oxy)dianilino]-4,4,6,6-tetrachlorocyclo-2 lambda(5),4 lambda(5),6 lambda(5)-triphosphazatriene(spiro) (2) and 2,2-[4,4'-(2,2'-(ethane-1,2-diylbis(oxy))bis(ethane-2,1-diyl))bis(oxy)dianilino]-4,4-bis(tertbutylamino)-6,6-dichlorocyclo-2 lambda(5),4 lambda(5),6 lambda(5)-triphosphazatriene (3) have been synthesized. The structures of the compounds (1, 2 and 3) are characterized by elemental analysis, IR, H-1, C-13, P-31 NMR and mass spectroscopic techniques. The antimicrobial activities of the compounds have been screened in vitro against the organisms. The structures of the compounds 1, 2 and 3 have also been examined by means of cyrstallographically. The compounds 1, 2 and 3 crystallize in the orthorhombic space group Pbca, hexagonal space group P4(3)2(1)2 and tetragonal space group P4(2)/n, respectively. They have unit cell parameters: a = 15.607(1), 10.6723(2) and 26.0308(9), b = 15.667(2), 10.6723(2) and 26.0308(9), c = 19.481(3), 23.3633(6) and 10.6033(4) angstrom, V = 4763.4(1), 2661.03(1) and 7184.8(4) angstrom(3), D-x = 1.570, 3.031 and 1.258 g cm(-3) and Z = 8, 8 and 8, respectively.
