irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...
متن کامل1-Allyl-3-amino-1H-pyrazole-4-carboxylic acid
The title compound, C(7)H(9)N(3)O(2), was prepared by alkaline hydrolysis of ethyl 1-allyl-3-amino-1H-pyrazole-4-carboxyl-ate. The crystal structure is stabilized by three types of inter-molecular hydrogen bond (N-H⋯O, N-H⋯N and O-H⋯N).
متن کامل5-Amino-1-(4-nitrophenyl)-1H-pyrazole-3-carbonitrile
The title compound, C(10)H(7)N(5)O(2), was synthesized by the reaction of 4-nitro-aniline and 2,3-dicyano-propionic acid ethyl ester. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional network.
متن کاملEthyl 5-amino-3-methylsulfanyl-1H-pyrazole-4-carboxylate
In the title compound, C(7)H(11)N(3)O(2)S, bond lengths and angles are within normal ranges. The crystal packing is stabilized by inter-molecular N-H⋯O hydrogen bonds, linking the mol-ecules into infinite one-dimensional chains along the a axis.
متن کامل5-Amino-3-anilino-1H-pyrazole-4-carbonitrile
In the title compound, C(10)H(9)N(5), the phenyl ring is twisted with respect to the pyrazole ring, forming a dihedral angle of 24.00 (6)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into chains running parallel to [010] containing alternating R(2) (2)(6) and R(2) (2)(12) rings. Further inter-actions are found in the crystal, viz. N-H⋯π(phen-yl) inter-actions and weak face-to...
