Abstract

Two new oxaspirocyclic compounds, 8-(4-(dimethylamino)benzylidene)-6,10-dioxaspiro[4.5]decane-7,9-dione (1) and 8-(4-hydroxybenzylidene)-6,10-dioxaspiro[4.5]decane-7,9-dione (2) have been synthesized and their structures determined by single crystal X-ray crystallography. Compound 1, C17H19NO4, belongs to the monoclinic system, space group P21/c with a = 6.2554(13) Å, b = 14.605(3) Å, c = 16.265(3) Å, β = 95.97(3)°, V = 1477.9(5) Å3, Z = 4, Dc = 1.354 g/cm3, F(000) = 640, μ(MoKa) = 0.097 mm−1, the final R = 0.0570 and wR = 0.1667. Compound 2, C15H14O5, is also of the monoclinic system, space group P21/c with a = 10.739(2) Å, b = 18.348(4) Å, c = 6.7799(14) Å, β = 104.20(3)°, V = 1295.1(5) Å3, Z = 4, Dc = 1.407 g/cm3, F(000) = 608, μ(MoKa) = 0.106 mm−1, the final R = 0.0568 and wR = 0.1739. Some C–H···O intra- and intermolecular hydrogen bonds and π··· π stacking interactions are both observed in the two lattice structures. The difference between them is that one type of C–H···π supramolecular interaction (1) and one type of O–H···O intermolecular hydrogen bond (2) are observed. View Full-Text
