5-Butyl-5-ethylbarbituric acid: a phase transition at low temperature.
The room-temperature crystal structure of 5-butyl-5-ethylbarbituric acid (generally known as butobarbitone), C10H16N2O3, was reported in space group C2/c [Bideau (1971). C. R. Acad. Sci. Paris Ser. C, 272, 757-760]. A redetermination at 120 K using synchrotron radiation shows the space group at this temperature to be P2(1)/n and not C2/c. There are two crystallographically independent molecules...
متن کامل5-tert-Butyl-2-[5-(5-tert-butyl-1,3-benzoxazol-2-yl)-2-thienyl]-1,3-benzoxazole
The title compound, C(26)H(26)N(2)O(2)S, was prepared by the reaction of thio-phene-2,5-dicarboxylic acid and 2-amino-4-tert-butyl-phenol. One of the tert-butyl groups is disordered over two conformations, with occupancies of 0.539 (1) and 0.461 (2). The two 1,3-benzoxazole rings are almost planar, with dihedral angles of 0.83 (18) and 1.64 (17)° between the five- and six-membered rings. The th...
متن کامل2-[(E)-(5-tert-Butyl-2-hydroxyphenyl)diazenyl]benzoic acid
The title compound, C(17)H(18)N(2)O(3), is approximately planar, owing in part to an intra-molecular bifurcated O-H⋯(N,O) hydrogen bond; the dihedral angle between the two aromatic rings is 23.86 (9)°. In the crystal struture, centrosymmetrically related mol-ecules associate into dimers via the eight-membered carboxyl-ate {⋯H-O-C=O}(2) synthon.

The title compound, C(16)H(23)NO(4), is essentially planar except for the last two C atoms in each n-butyl group (r.m.s. deviation from the least-squares plane = 0.02 Å for 17 non-H atoms). In the crystal, inter-molecular N-H⋯O hydrogen bonds between the amine and carbonyl groups link the mol-ecules into one-dimensional chains.
متن کامل[Co(NH3)5(NO3)](NO3)2 as an energetic coordination precursor for the preparation of Co3O4 nanoparticles at low temperature
In this paper, an energetic coordination compound namely pentamminenitratocobalt(III) nitrate, [Co(NH3)5(NO3)](NO3)2, was used as a new precursor for the preparation of Co3O4 nanoparticles. The results showed that the complex is easily decomposed into the Co3O4 nanoparticles at low temperature (200 °C) without employing a surfactant or solvent and any complicated equipment. The product was char...
