Crystal structure and Hirshfeld surface analysis of pulcherrin J
The title compound, C29H36O4 [systematic name (4aR,5R,6aS,7R,11aS,11bR)-4a-hydroxy-4,4,7,11b-tetramethyl-1,2,3,4,4a,5,6,6a,7,11,11a,11b-dodecahydrophen-anthro[3,2-b]furan-5-yl cinnamate], a natural diterpene known as pulcherrin J, was isolated from stem barks of medicinally important Caesalpinia pulcherrima (L.). The crystal structure of pulcherrin J shows it to be composed of a central core of...
متن کاملA new monoclinic polymorph of N-(3-methylphenyl)ethoxycarbothioamide: crystal structure and Hirshfeld surface analysis
The title compound, C10H13NOS, is a second monoclinic polymorph (space group P21/c, Z' = 2) of the previously reported C2/c (Z = 1) polymorph [Tadbuppa & Tiekink (2005 ▸). Z. Kristallogr. New Cryst. Struct. 220, 395-396]. Two independent mol-ecules comprise the asymmetric unit of the new polymorph and each of these exists as a thioamide-thione tautomer. In each molecule, the central CNOS chromo...
متن کاملm-Xylylenediaminium sulfate: crystal structure and Hirshfeld surface analysis
The crystal structure of the title salt {systematic name: [1,3-phenyl-enebis(methyl-ene)]bis-(aza-nium) sulfate}, C8H14N2 (2+)·SO4 (2-), consists of infinite (100) sheets of alternating organic and inorganic entities The m-xylylenediaminium cations are linked to the sulfate anions by N-H⋯O and asymmetric bifurcated N-H⋯(O,O) hydrogen bonds, generating a three-dimensional network. A weak C-H⋯O i...
متن کامل12-(3,4,5-Trimethoxyphenyl)-2,3,4,12-tetrahydro-1H-5-oxatetraphen-1-one: crystal structure and Hirshfeld surface analysis
In the title compound, C26H24O5, the pyran ring has a flattened-boat con-formation, with the 1,4-related ether O and methine C atoms lying 0.1205 (18) and 0.271 (2) Å, respectively, above the least-squares plane involving the doubly bonded C atoms (r.m.s deviation = 0.0208 Å). An envelope conformation is found for the cyclo-hexene ring, with the flap atom being the middle methyl-ene C atom, lyi...
متن کاملCrystal structure and Hirshfeld surface analysis of ethyl 5-phenylisoxazole-3-carboxylate
The title compound, C12H11NO3, is an inter-mediate used in the synthesis of many drug-like mol-ecules. The mol-ecule is almost planar, with the phenyl ring inclined to the isoxazole ring by 0.5 (1)°. The ester moiety has an extended conformation and is almost in the same plane with respect to the isoxazole ring, as indicated by the O-C-C-N torsion angle of -172.86 (18)°. In the crystal, mol-ecu...
