Description :
Mp: 715℃
bp : 1383℃
In its gas phase, RbCl is diatomic with a bond length estimated at 2.7868 ?. This distance increases to 3.285 ? for cubic RbCl, reflecting the higher coordination number of the ions in the solid phase.
Depending on conditions, solid RbCl exists in one of three arrangements or polymorphs as determined with holographic imaging
