We have investigated dielectric andmagnetodielectric properties of the geometrically frustrated spin -chain compound Ca{sub 3}CoRhO{sub 6}, which is known to undergo ‘partially disordered antiferromagnetic’ transition around 90 K (T{sub 1}) followed by another glassy magnetic transition around 30 K (T{sub 2}). We have observed dielectric glass behavior around 90 K, at the magnetic transition, which indicates that this behavior is predominantly magnetic in its origin. The magnetic field dependent dielectric constant in the magnetically ordered state tracks the features in isothermal magnetization thereby establishingmagnetodielectric coupling in this compound.
