Guanidinium tetracyanoplatinate

Partially oxidized tetracyanoplatinates have attracted much attention in recent years because of their highly anisotropic physical properties.1 Although partially oxidized salts of K+, Na+, Rb and Mg+2 have been reported, the analogous bromide-deficient guanidinium salt is the only such compound containing an organic cation.2 A procedure for the preparation of this guanidinium salt has not been previously reported. 

Summary. The potassium salts of tetracyanoplatinates are by far the most extensively studied highly conducting inorganic one-dimensional materials. The magnesium, sodium, guanidinium, and rubidium salts have been reported, but they have not been characterized to the extent that detailed comparisons can be made as a function of counter ions.
