Hello All,

Is it correct to write the compound U(As1-xSx)2 as UAs2-2xS2x?. So for x=0.5 the compound is UAs1S1.
Thanks, Rajini.

It can be right, but sometimes the first version (with (whatever)2) is meant to suggest composition of the compound.

So Ca(CN)2 and CaC2N2 both describe the composition of the same calcium cyanide, but the first formula is much more easy to read.

Could be there is a similar logic behind U(As1-xSx)2.
