The title compound, C23H24O3, was obtained in a one-step (60% yield) synthesis from 1,1,1-tris(hydroxymethyl)ethane. It features a tripodal ligand capable of complexing metal centres. One of the three conformations involving the methyl group, the central C-C bond and the phenoxy substituents is antiperiplanar while the two others are synclinal [the corresponding C-C-C-O torsion angles are -174....
In the heterocyclic title compound, C(17)H(19)N(5)O(3), the quinazolinone ring system forms a dihedral angle of 67.22 (7)° with the triazole ring. The butyl acetate group has a non-linear conformation, with an alternation of synclinal and anti-periplanar torsion angles [N-C-C-C = 58.5 (2)°, C-C-C-C = 170.72 (19)° and C-C-C-O = -65.9 (3)°]. The crystal structure features inter-molecular C-H⋯N an...
[structure: see text] Ferrocene compounds bearing multiple amido groups selectively bind with the H(2)PO(4)(-) ion over other anions. The one-arm receptors form 1:1 complexes with the H(2)PO(4)(-) ion, whereas the two-arm receptors can accommodate two H(2)PO(4)(-) ions. The complexation modes and binding strengths are deduced from the NMR, calorimetry, fluorescence, and cyclic voltammetry studi...
-First generation structures in greywackes of the Yuso Group from the Cantabrian Mountains of northern Spain show a distinct variation in geometry with depth in a regional synclinal structure (Curavacas and Lechada synclines); they are easily distinguished from other deformation events. In the structurally uppermost level we find 'flap folds'. Flap folds are recumbent structures with the invert...
The title benzohydrazide derivative, C(17)H(18)N(2)O(5), exists in a trans conformation with respect to the C=N double bond. The dihedral angle between the benzene rings is 19.41 (5)°. The two meth-oxy groups at the meta positions of the trimeth-oxy-benzene group are almost coplanar with the ring [C-O-C-C = 1.62 (16) and 178.33 (10)°], whereas the third meth-oxy group, at the para position, is ...
Through a survey of macrofungi in Ghalajeh heights and its surrounding plains, conducted from 2014- 2017, twelve specimens of macroascomycota were collected. The specimens were identified on the basis of macro- and micro-morphological characteristics. The internal transcribed spacer sequences of the selected specimens were analyzed to confirm the morphological identification. Based on the resul...
Mol-ecules of the title amino-chalcone, C(18)H(19)NO(4), are twisted, with a dihedral angle of 11.26 (6)° between the 4-amino-phenyl and 2,4,5-trimeth-oxy-phenyl rings. The conformations of the three meth-oxy groups with respect to the benzene ring are slightly different. Two meth-oxy groups are almost coplanar with the attached benzene ring [C-O-C-C torsion angles of -1.45 (19) and 1.5 (2)°], ...
Adamantyl-based compounds are commercially important in the treatments for neurological conditions and type-2 diabetes, aside from their anti-viral abilities. Their values in drug design are chronicled as multi-dimensional. In the present study, a series of 2-(adamantan-1-yl)-2-oxoethyl benzoates, 2(a-q), and 2-(adamantan-1-yl)-2-oxoethyl 2-pyridinecarboxylate, 2r, were synthesized by reacting ...
