✦ Synopsis

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) Å, c = 17.872(5) Å, α = 65.957(7)°, β = 83.603(5)°, γ = 75.242(5)°, V = 2549.8(13) Å 3 , Z = 4, and D =1.374 g/cm 3 . The compound consists of a quinazolinone ring with phenol and tributylstannyl moieties. Compound II crystallizes in the monoclinic space group P2 1 /c with a = 7.6454(12) Å, b = 5.9270(9) Å, c = 27.975(4) Å; α = 90°, β = 95.081(3)°, γ = 90°, V = 1262.7(3) Å 3 , Z = 4, and D = 1.915 g/cm 3 . 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.
