Cristalline structure of 2-[4-phenyl-5,5-dimethyl-4,5-dihydro-3H-pyrazol-3-YL]-5,5-dimethyl-2-(naphtalene-2-YL)-2,5-dihydro-(1,3,4)oxadiazole, C25H26N4O
Written by sctunisie no commentsC25H26N4O, Mr = 398.50 g.mol-1, crystallizes in the orthorhombic system, space group P212121. The cell parameters are: a = 8.301(2) Å ; b = 11.539(2) Å ; c = 22.976(4) Å, V = 2200.8(8) Å3, with Z = 4. The molecular groups are organized in corrugated layers perpendicular to the c direction. The intramolecular linkage into and between thoose layers, is performed by Van Der Waals interactions N...H and O...H. The crystallographic study of the title compound has enabled us to confirm the unexpected molecular structure deduced from NMR study.
