Refinement of the crystal structure of UOs₂ from single-crystal X-ray diffraction data

Refinement of the crystal structure of UOs₂ was performed for the first time by using single-crystal X-ray diffraction data, which allowed the refinement of all U^ij terms of the displacement parameters.

{Bis[2-(pyridin-2-yl)eth­yl]amine}­dibromidocopper(II)

Two molecules with slightly different five-coordinate Cu^II atoms are present in the asymmetric unit of thetitle complex.

Chlorido­((E)-2-{2-[(2-hy­droxy­benzyl­idene)amino]-2-(pyridin-2-yl)-1-[(pyridin-2-ylmeth­yl)amino]eth­yl}phenolato-κ⁴N,N′,N′′,O)copper(II)

The title copper(II) complex shows the central Cu^II cation to be in a slightly distorted square-pyramidal coordination by the [ClN₃O] coordination set.
