Crystal structure of 2-(2'-hydroxyphenyl)-6-tributylstannyl-4-(3H )-quinazolinone and 2-(2'-hydroxyphenyl)-6-iodo-4-(3H)-quinazolinone

Abstract

The structures of the title compounds C 26 H 37 N 2 O 2 Sn (I) and C 14 H 9 IN 2 O 2 (II) were determined by singlecrystal X-ray diffraction technique. Compound I crystallizes in the triclinic space group P1 with a = 9.560(3) Å, b = 16.899 (6) . The compound consists of a quinazolinone ring with phenol and iodine substituents. For both I and II, the short intramolecular O-H…N and two long intermolecular N-H…O hydrogen bonds are highly effective in holding the molecular system in a stable state.
