The title compound, [Fe(C7H9N2)2], crystallizes with two crystallographically independent mol-ecules in the unit cell. These represent the chiral atropoisomers distinguished by the mutual arrangement of the two acet-yl-hydrazone groups with a cis conformation of the C=N bonds. The two cyclo-penta-dienyl (Cp) rings are planar and nearly parallel, the tilt(More)
The cyclo-hexene ring that constitutes a part of the tetra-hydroxanthene fused-ring system of the title compound, C(23)H(26)O(4), adopts a flattened half-chair conformation that approximates an envelope conformation (in which the methyl-ene C atom bearing the two methyl substituents represents the flap) as five of the six atoms lie approximately on a plane(More)
In the title compound, C(8)H(10)N(2), the cyclo-hexane ring adopts a chair conformation. he crystal structure of the previously reported monoclinic modification have intramolecular CN⋯CN and C-H⋯N interactions. These types of interaction are not present in this new modification whose crystal structure is built up by van der Waals interactions.
The title compound, C(26)H(28)N(2)O(9)·1.5H(2)O, the product of an acid-catalysed Wagner-Meerwein skeletal rearrangement, crystallizes as a sesquihydrate with the O atom of one of the two independent water mol-ecules occupying a special position on a twofold axis. The organic mol-ecule comprises a fused penta-cyclic system containing two five-membered rings(More)
In the title compound, [Cu(C(8)H(4)F(3)O(2)S)(2)(C(10)H(14)N(2)O)], the Cu(II) atom exists in a distorted CuNO(4) square-pyramidal geometry; the metal atom lies above a square plane defined by four O atoms of the two chelating anionic ligands, displaced in the direction of the axial occupant, the pyridine N atom, by 0.179 (1) Å. Weak inter-molecular C-H⋯O(More)
In the title compound, C(24)H(35)NO(2), the planes of the two aromatic rings form a dihedral angle of 72.76 (4)°. In the crystal, mol-ecules are linked by O-H⋯O and O-H⋯N hydrogen-bond inter-actions, forming an extended two-dimensional framework parallel to the ab plane.
The title compound, the product of an acid-catalysed Wagner-Meerwein skeletal rearrangement, crystallizes as an ethanol monosolvate, C(20)H(21)NO(8)·C(2)H(6)O. The title mol-ecule comprises a fused tricyclic system containing two five-membered rings (cyclo-pentane and tetra-hydro-furan) in the usual envelope conformations and one six-membered ring(More)

The asymmetric unit of the title compound, C(25)H(22)N(2)O, contains two independent mol-ecules (A and B), with significantly different conformations. In mol-ecule A, the central imidazole ring makes dihedral angles of 88.26 (10) and 12.74 (11)° with the two phenyl rings, and 22.06 (9)° with the benzene ring. In mol-ecule B, one of the phenyl rings is(More)
