Bis(morpholin-4-ium) tetra­chlorido­cobalt(II)

The title compound, (C₄H₁₀NO)₂[CoCl₄], is an ionic compound consisting of two protonated tetra­hydro-1,4-oxazine (morpholine) cations and a [CoCl₄]²⁻ dianion. The Co^II ion is in a tetra­hedral coordination geometry. The cations exhibit chair-shaped conformations. A three-dimensional supra­molecular architecture is formed through N—H...Cl and C—H...Cl hydrogen bonds between the dianions and the cations.

trans-Iodido(pyrazinyl-κC²)bis­(triphenyl­phosphane-κP)palladium(II)

There are two independent mol­ecules with similar configurations in the asymmetric unit of the title complex, [Pd(C₄H₃N₂)I(C₁₈H₁₅P)₂]. In each mol­ecule, the geometry around the Pd atom is distorted square-planar, with the Pd atom displaced by 0.0549 (12) and 0.0734 (13) Å from the least-squares plane of the I—P—P—C atoms. The PPh₃ ligands are in trans positions, with P—Pd—P angles of 173.12 (4) and 170.29 (4)°, while the pyrazinyl ligands and I atoms, also trans to each other, form C—Pd—I angles of 179.38 (12) and 178.44 (12)°. In the crystal, C—H...π inter­actions occur, resulting in a three-dimensional supramolecular architecture.
