Structural studies on molecular complexes of polyethers. 4 Deoxycholic acid-polyether complexes

Complexes of deoxycholic acid with polyethers, –(CH₂) _m–1CHR–O–] _n (R=H,m=2–4, 6 andR=CH₃,m=2), were prepared. The crystals are orthorhombic and similar to those most commonly observed for complexes with low molecular weight molecules. Dimensiona in the poly(propylene oxide) complex is about 1 Å longer than those in other polyether complexes, whileb andc do not differ much in these DCA-polyether complexes.
