Synthesis, crystal structure and magnetic properties of the new ternary indides REPd2In4 (REÂ =Â La, Ce, Pr, Nd)

► New ternary indides REPd2In4 (RE = La, Ce, Nd, Pr) with a new structure type. ► The new structure type is formed of two structures: YbAu2In4 and SmPd2In4. ► LaPd2In4 is a weak diamagnet. ► CePd2In4, PrPd2In4, and NdPd2In4 exhibit Curie-Weiss paramagnetism.
