In the title compound, C18H14N2O5, the pyrrolidine ring adopts a shallow envelope conformation, with the C atom bearing the OH group (and remote from the N atom) displaced by 0.257 (2) Å from the other atoms. The cyclo-pentane ring has a twisted conformation about the C-C bond bearing one =O and one -OH grouping. The dihedral angle between the five-membered rings (all atoms) is 65.54 (9)° and t...

In the title compound, [Fe(C5H5)(C32H23FN3OS)], both the thia-zolidine ring and the pyrrolidine ring adopt a twist conformation on the N-C(H) bridging bond. Their mean planes are inclined to one another by 10.05 (10)°, and they make dihedral angles of 82.09 (10) and 89.67 (11)°, respectively, with the cyclo-pentane ring. The F atom deviates by -0.0238 (2) Å from the benzene ring to which it is ...

A tripodal amido ligand with a central non-chelating phosphorus donor allows for the facile assembly of a pentane soluble organometallic copper cluster with a central copper atom surrounded by a nonplanar chain of eight copper atoms and two terminal amido-copper bonds.

The asymmetric unit of the title compound, C(9)H(11)ClN(4), contains two virtually planar mol-ecules that differ in conformation about the bond connecting the hydrazine and pyridazine units. The 3-chloro-6-hydrazinylpyridazine and cyclo-pentane groups are oriented at dihedral angles of 4.5 (3) and 8.8 (4)° in the two mol-ecules. In the crystal, the mol-ecules form a one dimensional polymeric st...

Studi ini membahas peluang pemanfaatan panasbumi temperatur rendah keluaran wellpad di Pulau Ambon sebagai pembangkit listrik tenaga baru menggunakan siklus biner.

Platinum, palladium, and copper catalysts supported on precipitated silica have been studied for the hydrodeoxygenation and hydrogenation of 2-methyl-2-pentenal in the 200–400 C temperature range. The activity follows the order Pt > Pd > Cu. It has been found that at low temperatures, Pt and Pd are primarily active for the hydrogenation of the C@C bond to make 2-methyl-pentanal, with some decar...

In the title polymeric compound, [Cd(C(9)H(12)O(4))(C(10)H(8)N(2))](n), the Cd(II) atom is located on a twofold rotation axis and is coordinated by two 4,4'-bipyridine ligands and two 2,2-dimethyl-cyclo-pentane-1,3-dicarboxyl-ate ions. The carboxyl-ate ion and the N-heterocycle both function as bridges to link adjacent Cd(II) atoms to result in the formation of a layer structure parallel to (01...

The asymmetric unit of the title compound, [H(3)N(CH(2))(5)NH(3)](2)I[I(3)](3) or 2C(5)H(16)N(2) (2+)·3I(3) (-)·I(-), consists of two crystallographically independent pentane-1,5-diaminium dications and two triiodide anions in general positions besides two additional triiodide and two iodide anions located on twofold axes. The compound crystallizes in the centrosymmetric monoclinic space group ...

The pentane σ-complex [Rh{Cy2 P(CH2 CH2 )PCy2 }(η(2) :η(2) -C5 H12 )][BAr(F) 4 ] is synthesized by a solid/gas single-crystal to single-crystal transformation by addition of H2 to a precursor 1,3-pentadiene complex. Characterization by low temperature single-crystal X-ray diffraction (150 K) and SSNMR spectroscopy (158 K) reveals coordination through two Rh⋅⋅⋅H-C interactions in the 2,4-positio...
