A new lanthanum(III) complex containing acetylacetone and 1H-imidazole
In the title complex, di-aqua-(1H-imidazole-κN3)(nitrato-κ2O,O')bis-(4-oxo-pent-2-en-2-olato-κ2O,O')lanthanum(III), [La(C5H7O2)2(NO3)(C3H4N2)(H2O)2], the La atom is coordinated by eight O atoms of two acetyl-acetonate (acac) anions acting as bidentate ligands, two water mol-ecule as monodentate ligands, one nitrate anions as a bidentate ligand and one N atom of an imidazolate (ImH) molecule as ...
متن کامل4-Phenyl-1H-imidazole (a low-temperature redetermination), 1-benzyl-1H-imidazole and 1-mesityl-1H-imidazole.
Low-temperature studies of the simple variously substituted imidazole types 4-phenyl-1H-imidazole, C9H8N2, 1-benzyl-1Himidazole, C10H10N2, and 1-mesityl-1H-imidazole, C12H14N2, extend comparisons between parent imidazole species and their derivatives, the pronounced double-bond localization opposite the substituted N atom common to simple neutral species being redistributed aromatically on prot...
متن کامل1-Ferrocenylmethyl-1H-imidazole
In the title compound, [Fe(C(5)H(5))(C(9)H(9)N(2))], the distances of the Fe atom from the centroids of the unsubstituted and the substituted cyclo-penta-dienyl (cp) rings are 1.639 (1) and 1.647 (1) Å, respectively. The ferrocenyl unit deviates from an eclipsed geometry with tilted cp rings; the inter-planar angle between the cp and imidazole rings is 114.11 (4)°.
متن کامل2-Phenyl-1H-imidazole
In the title compound, C(9)H(8)N(2), a mirror plane lies perpendicular to the phenyl and imidazole rings and passes through the bridging C-C bond, so that the imidazole ring is disordered over two sites about the mirror plane with the equal site occupancy; the asymmetric unit contains one half-mol-ecule. In the crystal, adjacent mol-ecules are linked via N-H⋯N hydrogen bonds.
متن کامل1,2,4,5-Tetraphenyl-1H-imidazole
The asymmetric unit of the title compound, C(27)H(20)N(2), contains two independent mol-ecules, A and B. In both mol-ecules, the N atom in the 1-position and the C atom in the 5-position are statistically disordered [as 0.571 (8):0.429 (8) in A and 0.736 (9):0.264 (9) in B]. The phenyl rings in the 1-, 2-, 4- and 5-positions in A are twisted from the central imidazole ring by 84.3 (2), 21.6 (2)...
