The mol-ecule of the title compound, C(66)H(40)F(6)·CH(2)Cl(2), is centrosymmetric; the dihedral angle between the central fluorinated unit and the cyclo-penta-diene ring is 88.36 (7)°. The dihedral angles between the cyclo-penta-diene ring and the four surrounding phenyl rings are in the range 26.6 (1)-65.6 (1)°. Centrosymmetric cavities in the crystal structure are populated by disordered dic...

In the title compound, C(26)H(24), 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-heptane substituents. These substituents comprise the pommel and cantle, with each mean plane defined by four atoms proximate to the seat (r.m...

Tonsillectomy is one of the most common operative procedures in childhood. According to the Croatian national guidelines for the treatment of sore throat (ISKRA guidelines), apsolute indications for tonsillectomy are recurrent tonsillitis (>4 per year) and sleep disordered breathing (including snoring and obstructive sleep apnea). Most children in Croatia undergo conventional cold steel tonsill...

The title compound, C(6)Cl(10), cystallizes in a nearly C2-symmetrical gauche conformation. Both trichloro-vinyl groups are nearly planar [Cl-C-C-Cl torsion angles = -178.47 (12) and -179.93 (11)°] and the lengths of their C-Cl bonds increase from the terminal trans and cis C-Cl bonds to the inter-nal bonds. The Cl-C-Cl bond angles of the terminal dichloro-methyl-ene units are compressed to 111...
متن کاملBis{[2,2′-(5,8,11-trithia-2,14-diazapentadeca-1,14-diene-1,15-diyl)diphenolato]palladium(II)} acetonitrile monosolvate
The asymmetric unit of the title compound, [Pd(C22H26N2O2S3)]2·CH3CN, contains two complex mol-ecules and a single uncoordinated lattice aceto-nitrile solvent mol-ecule. The Pd(II) cations have a trans-N2O2 square-planar geometry and the superposition of the two crystallographically independent Pd(II) complexes yields an overall r.m.s. deviation of 0.292 Å. The Pd⋯Pd separation in the asymmetri...
