Ten new 2-(3-aryl-1-phenyl-4-pyrazolyl)benzoxazoles have been synthesized by oxidative intramolecular cyclization of the corresponding Schiff's bases using iodobenzene diacetate in methanol as an oxidant.

In the polymeric title complex, [Zn(C(10)H(8)O(4)S(2))(C(10)H(8)N(2))(H(2)O)(2)](n), the Zn(2+) ion lies on a twofold rotation axis and exhibits an octa-hedral environment, in which it is coordinated by two trans O atoms from two symmetry-related 2,2'-[1,4-phenyl-enebis(sulfanedi-yl)]diacetate anions, two N atoms from one 2,2'-bipyridine ligand, and two cis O atoms from water mol-ecules. The di...
