A novel Schiff base compound, C(20)H(27)NO(2), was obtained by a condensation of rimantadine and 2-hy-droxy-4-meth-oxy-benzaldehyde. An intra-molecular O-H⋯N hydrogen bond supports the phenol-imine tautomeric form. The adamantane and imino-methyl-4-meth-oxy-phenol units are arranged in a folded conformation [C-N-C-C torsion angle = 110.9 (3)°]. In the crystal, highly hydro-phobic adamantane moi...

In the crystal structure of the title compound, C(11)H(10)N(2)O(3), inversion-related mol-ecules are connected by pairs of O-H⋯O hydrogen bonds. With the exception of the atoms in the carb-oxy-lic acid group, the non-H atoms are roughly coplanar with a maximum deviation from the mean plane of 0.270 (1) Å for the C atom to which the carb-oxy-lic group is attached. The C atom of the carb-oxy-lic ...

In the title compound, C(14)H(12)ClNO(2), the chloro- and meth-oxy-substituted benzene rings are close to orthogonal [dihedral angle = 79.20 (3)°]. These rings also make angles of 45.9 (3) and 33.5 (3)° with the amide -CONH- unit. The meth-oxy substituent lies close to the meth-oxy-benzene ring plane, with a maximum deviation of 0.142 (3) Å for the methyl C atom. The N-H bond is anti to the 2-c...

The present study evaluated the impact of chronic herbicide (oxyfluorfen; OXY) exposure on catfish, Clarias gariepinus, in terms growth, hematobiochemical parameters, immune response, antioxidant- and immune-related gene expression, resistance to monogenean parasites, Quadriacanthus aegypticus. In addition, protective role Wormwood, Artemisia cina (AC) against OXY through diet inclusion was als...

Three coumarin derivatives, viz. 6-methyl-N-(3-methyl-phen-yl)-2-oxo-2H-chromene-3-carboxamide, C18H15NO3 (1), N-(3-meth-oxy-phen-yl)-6-methyl-2-oxo-2H-chromene-3-carboxamide, C18H15NO4 (2), and 6-meth-oxy-N-(3-meth-oxy-phen-yl)-2-oxo-2H-chromene-3-carboxamide, C18H15NO5 (3), were synthesized and structurally characterized. The mol-ecules display intra-molecular N-H⋯O and weak C-H⋯O hydrogen bo...

The title compound, [Fe(C(2)H(5)O)(C(36)H(44)N(4))], contains a five-coordinate iron-porphyrin complex with an axial eth-oxy ligand. The iron(III) atom is displaced by 0.504 (2) Å towards the eth-oxy ligand from the 24-atom mean plane of the porphyrin. The average Fe-N(p) distance is 2.078 (2) Å and the Fe-O distance is 1.8232 (18) Å. The eth-oxy C atoms are disordered in a 0.581 (12):0.419 (12...

The asymmetric unit of the title compound, C(22)H(28)N(2)O(3)·CH(4)O, consists of two independent Schiff base mol-ecules and two independent methanol solvent mol-ecules. In one Schiff base mol-ecule, the 2-hydr-oxy group forms an intra-molecular hydrogen bond with the amide O atom, whereas in the other Schiff base mol-ecule, the 2-hydr-oxy-substituted benzene ring is oriented so that the 2-hydr...

In the title compound, C(13)H(18)ClNO(4), the two meth-oxy groups at the meta positions of the attached benzene ring are close to being coplanar with the ring [the meth-oxy C atoms deviate by 0.267 (7) and 0.059 (7) Å], whereas the third meth-oxy group at the para position is not coplanar with the benzene ring [methoxy C atom deviates by 1.100 (6) Å]. In the crystal, mol-ecules are linked into ...

Although 6-azido-6-de-oxy-l-galactose in aqueous solution is in equilibrium between the open-chain, furan-ose and pyran-ose forms, it crystallizes solely as 6-azido-6-de-oxy-α-l-galactopyran-ose monohydrate, C(6)H(11)N(3)O(5)·H(2)O, with the six-membered ring adopting a chair conformation. The structure exists as hydrogen-bonded chains, with each mol-ecule acting as a donor and acceptor of five...

The racemic title compound, C(9)H(11)NO(4)·H(2)O, a tricyclic rearranged amino-norbornane dicarb-oxy-lic acid, is a conformationally rigid analogue of glutamic acid and exists as an ammonium-carboxyl-ate zwitterion, with the bridghead carb-oxy-lic acid group anti-related. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds involving the ammonium, carb-oxy-lic acid and water donor groups with both wa...
