Triaqua[2,2′-(propane-1,3-diyl)bis(5-carboxy-1H-imidazole-4-carboxylato-κ2 N 3,O 4)]calcium(II) tetrahydrate
In the title compound, [Ca(C(13)H(10)N(4)O(8))(H(2)O)(3)]·4H(2)O, the Ca(II) ion is hepta-coordinated by two N atoms and two O atoms from a tetra-dentate 1,3-bis-(1H-imidazole-4,5-dicarb-oxy-l-ate) propane dianion and three water O atoms, giving a distorted penta-gonal-bipyramidal coordination environment. The Ca-O bond lengths are in the range 2.354 (3)-2.453 (2) Å, while the Ca-N bond lengths...
متن کاملCondensation of thiohydrazide analogues with 4-bromo-3, 6-dichloropyridazine: an efficient rout to pyridazino[4, 3-e][1, 3, 4] thiadiazines
Abstract- Some new 3-(alkylsulfanyl)- 7-chloro-1-phenyl-1H-pyridazino [4,3-e][1,3,4]thiadiazine were synthesized by treatment of the alkyl-2-phenylhydrazinecarbodithioates with 4-bromo-3,6-dichloropyridazine in alkaline acetonitril. Orientation of the reaction has been determined by X-Ray crystallography technique. The chlorine atom on the number 7 position of these products was repla...

متن کامل3′,4′-Dimethoxybiphenyl-4-carbonitrile
The title compound, C(15)H(13)NO(2), was prepared through a palladium-catalysed Suzuki-Miyaura coupling reaction. The dihedral angle between the biphenyl rings is 40.96 (6)°. The meth-oxy groups are twisted slightly out of the plane of the benzene ring [C-C-C-C torsion angles = -3.61 (18) and 12.6 (2)°]. The packing of the molecules is stabilized by van der Waals inter-actions.
متن کامل3-(4-Chlorobenzoyl)-4-(4-chlorophenyl)-1-phenethylpiperidin-4-ol
In the title compound, C(26)H(25)Cl(2)NO(2), the piperidine ring adopts a chair conformation with a cis configuration of the carbonyl and hy-droxy substituents. The dihedral angle between the aromatic rings of the chloro-benzene groups is 24.3 (2)°. The phenyl ring forms dihedral angles of 59.4 (3) and 44.1 (3)° with the benzene rings. In the crystal, mol-ecules are linked by inter-molecular O-...
