Diversity of Crystal Structures in a System Containing Complex Ions [Pt(NH3)4]2+ and [Rh(C2O4)3]3
Numerous crystal products with different ratios of complex ions can be obtained by varying the conditions of double complex salts precipitation from aqueous solutions containing [Pt(NH 3 ) 4 ](NO 3 ) 2 and Na 3 [Rh(C 2 O 4 ) 3 ]. Since all these salts are crystal hydrates, the variety of obtained cr...
