Molybdenum Complexes Derived from 2-Hydroxy-5-nitrobenzaldehyde and Benzhydrazide as Potential Oxidation Catalysts and Semiconductors.

This study aimed to synthesize molybdenum complexes coordinated with an aroyl hydrazone-type ligand (HL), which was generated through the condensation of 2-hydroxy-5-nitrobenzaldehyde with benzhydrazide. The synthesis yielded two types of mononuclear complexes, specifically [MoO(L)(MeOH)] and [MoO(L)(HO)], as well as a bipyridine-bridged dinuclear complex, [(MoO(L))(4,4'-bpy)]. Those entities were thoroughly characterized using a suite of analytical techniques, including attenuated total reflectance infrared spectroscopy (IR-ATR), elemental analysis (EA), thermogravimetric analysis (TGA), and single-crystal X-ray diffraction (SCXRD).

Combined experimental and computational study of cis-trans isomerism in bis(L-valinato)copper(II).

Heating of polycrystalline cis aquabis(L-valinato)copper(II) at 90 °C resulted in a dehydrated powder. Recrystallization from aqueous solution of the obtained product yielded anhydrous trans bis(L-valinato)copper(II). The X-ray crystal and molecular structures of trans bis(L-valinato)copper(II) and cis aquabis(L-valinato)copper(II) are presented.

Dicyclo-hexyl-ammonium 2-methoxy-benzoate.

The asymmetric unit of the title compound, C(12)H(24)N(+)·C(8)H(7)O(3) (-), contains one dicyclo-hexyl-ammonium cation and one 2-methoxy-benzoate anion. Two cations and two anions are linked together to form a four-ion cluster through a set of N-H⋯O hydrogen bonds. Weak C-H⋯O hydrogen bonds connect the clusters into chains that are stacked along the crystallographic c axis.

Propane-2,2-diyl di-p-phenyl-ene dibenzoate.

The V-shaped propeller-like mol-ecule of the title compound, C(29)H(24)O(4), does not exhibit crystallographic twofold symmetry as the two benzene rings are twisted asymmetrically with respect to both the central propyl plane and the benzo-yloxy groups [4.6 (2), 43.6 (2)° and 45.
