Crystal structure of bis(cyclohexylammonium) diphenyldioxalatostannate(IV)

2015

In the title salt, (CyNH3)2[Sn(Ph2)(C2O4)2] (Cy is cyclo­hexyl and Ph is phen­yl), the SnPh2 moiety is chelated by two oxalate anions, leading to a cis arrangement within the distorted octa­hedral coordination sphere of the SnIV atom.
