چکیده
In the title compound, C(32)H(28), the central cyclo-octa-tetra-ene ring has a boat conformation, and the mol-ecule is saddle shaped. The seat is defined by the mean plane of the four-atom attachment points (r.m.s. deviation = 0.014 Å) of the two bicyclo-heptenyl substituents. These substituents comprise the pommel and cantle, with each mean plane defined by four atoms proximate to the seat (r.m.s. deviations = 0.002 and 0.004 Å). Relative to the seat, the pommel and cantle bend up 31.16 (4) and 29.40 (5)°, while the benzo units (flaps, r.m.s. deviations = 0.006 and 0.009 Å) bend down 36.75 (4) and 38.46 (4)°. The mean planes of the dimethyl-ethyl-idene units are almost perpendicular to the saddle seat, making dihedral angles 86.89 (4) and 88.01 (4)°.

The title complex, [Cu(2)(C(22)H(20)Br(2)N(4)O(2))(ClO(4))(2)], was prepared by the condensation of 2,6-diformyl-4-bromo-phenol with 1,3-diamino-propane in the presence of copper(II) ions. The macrocyclic ligand shows an approximately planar structure except for the two propene groups in the macrocycle. The coordination polyhedron of each Cu atom can be described as distorted square pyramidal. ...

In the title compound, C(7)H(9)ClN(4), the 3-chloro-6-hydrazinylpyridazine unit is planar (r.m.s. deviation = 0.0219 Å) and is oriented at a dihedral angle 4.66 (27)° with respect to the propan-2-yl-idene group. In the crystal, the mol-ecules are linked into non-planar dimers due to a crystallographic twofold rotation via N-H⋯N hydrogen bonds with R(2) (2)(8) graph-set ring motifs.

The title compound, C13H13Cl2NO, has a 3-(propan-2-yl-idene)indolin-2-one core with a Cl atom and a chloro-ethyl substituent attached to the aromatic ring. Two atoms of the aromatic ring and the chloro-ethyl substituent atoms are disordered over two sets of sites with a refined occupancy ratio of 0.826 (3):0.174 (3). In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, formin...

In the title compound, C(14)H(21)FNO(6)P, a staggered conformation about the central P-C bond occurs, with the oxo and hydroxyl groups occupying diagonally opposite positions. The crystal structure features supra-molecular chains mediated by O-H⋯O hydrogen bonds, which propagate in the a-axis direction. A C-H⋯O inter-action consolidates the chains. Disorder was resolved for one of the isopropyl...
