3,5-Dinitropyridin-4(1H)-one monohydrate
The three independent organic mol-ecules of 3,5-dinitro-pyridin-4(1H)-one monohydrate, C(5)H(3)N(3)O(5)·H(2)O, each feature an N-H⋯O(water) hydrogen bond. Each water mol-ecule serves as hydrogen-bond donor to two carbonyl O atoms; these hydrogen bonds give rise to a layer motif. Two of the three formula units lie on special positions of site symmetry 2.
متن کامل2-Hydroxy-1-methoxyxanthen-9-one monohydrate
In the title compound, C(14)H(10)O(4)·H(2)O, isolated from the roots of Calophyllum membranaceum, the xanthene ring system is almost planar (r.m.s. deviation = 0.008 Å). In the crystal structure, inter-molecular O-H⋯O and O-H⋯(O,O) hydrogen bonds connect the mol-ecules.
متن کامل1-Phenyl-5-[4-(trifluoromethyl)phenyl]pyrazolidin-3-one monohydrate
In the mol-ecule of the title compound, C(16)H(13)F(3)N(2)O·H(2)O, the two benzene rings are oriented at a dihedral angle of 82.55 (3)° and the pyrazole ring adopts an envelope conformation. In the crystal structure, inter-molecular C-H⋯F hydrogen bonds link the mol-ecules into chains.
متن کامل5-Cyclohexyl-4-methyl-1H-pyrazol-3(2H)-one monohydrate
In the title compound, C(10)H(16)N(2)O·H(2)O, the cyclo-hexane ring is in a chair conformation and its least-squares plane makes a dihedral angle of 53.68 (5)° with the approximately planar pyrazole ring [maximum deviation = 0.034 (1) Å]. Pairs of inter-molecular N-H⋯O hydrogen bonds form inversion dimers between neighbouring pyrazolone mol-ecules, generating R(2) (2)(8) ring motifs. The pyrazo...
متن کامل7-Amino-1,8-naphthyridin-2(1H)-one monohydrate
In the crystal structure of the title compound, C(8)H(7)N(3)O·H(2)O, adjacent organic mol-ecules are linked together into a tape along the a axis through N-H⋯N and N-H⋯O hydrogen bonds. On the other hand, water mol-ecules are linked together to form a chain along the b axis through O-H⋯O hydrogen bonds. The water chains and the organic mol-ecular tapes are further connected by inter-molecular O...
