Radiolysis of Crystalline Oxalato Complexes [PDF]
Several crystalline metal oxalato complexes were irradiated with Co/sup 6//sup 0/ gamma rays. Oxalate ions such as in sodium oxalate and ferrous oxalate were found to be very stable to gamma radiation, compared with those in metal oxalato complexes. Oxalate ions with large covalent character are decomposed more easily by gamma radiation.

Poly[methylamine-μ-oxalato-copper(II)] [PDF]
The six-coordinate copper(II) ions in the title compound, [Cu(C2O4)(CH5N)], experience a Jahn-Teller distortion. The structure is a two-dimensional coordination network, with three crystallographically independent oxalate ions, two of them centrosymmetric, bridging CuII ions in three different coordination modes.

Bis(cyclohexylammonium) tetrachlorido(oxalato)stannate(IV) [PDF]
The title salt, (C6H14N)2[Sn(C2O4)Cl4], was obtained as a by-product from the reaction between 2C6H14N(+)·C2O4 (2-)·1.5H2O and SnCl2·2H2O. The cyclo-hexyl-ammonium cation has a chair conformation. The complex anion consists of an oxalate anion chelating the SnCl4 moiety, resulting in a distorted octa-hedral coordination sphere of the Sn(IV) atom with ...
