چکیده
The title salt, [K(2)(C(16)H(12)O(6))](n), was obtained by the reaction of 1,2-bis-[4-(ethyl-carbox-yl)-phenox-yl]ethane with KOH in water. The anion lies on a crystallographic inversion center, which is located at the mid-point of the central C-C bond. The K(+) cation is coordinated by six O atoms, two from the chelating carboxyl-ate group of the anion and four from four neighboring and monodentately binding anions, giving rise to an irregular [KO(6)] coordination polyhedron. The coordination mode of the cation leads to the formation of K/O layers parallel to (100). These layers are linked by the nearly coplanar anions (r.m.s. deviation of 0.064 Å of the carboxyl, aryl and O-CH(2) groups from the least-squares plane) into a three-dimentional network.

In the title compound, [Co(C(17)H(14)O(6))(C(12)H(8)N(2))(H(2)O)](n), the Co(II) atom is coordinated by a monodentate 4,4'-(propane-1,3-diyldi-oxy)dibenzoate (cpp) dianion, a water mol-ecule and a chelating 1,10-phenanthroline (phen) ligand. A symmetry-generated cpp ligand completes the CoN(2)O(3) trigonal-bipyramidal geometry for the metal ion, with the N atoms occupying both equatorial and ax...

The title compound, C(20)H(22)O(6), was obtained by the reaction of ethyl 4-hy-droxy-benzoate with 1,2-dichloro-ethane in dimethyl-formamide. The mol-ecule lies around the crystallographic inversion center at (0,0,0), with the asymmetric unit consisting of one half of the mol-ecule. The two ethyl groups are in trans positions. The ethyl, carboxyl, aryl and O-CH(2) groups are coplanar with an r....
