Two Three-Dimensional 2p−3d−4f Heterometallic Frameworks Featuring a Ln6Cu24Na12 Cluster as a Node

Two three-dimensional 2p−3d−4f heterometallic frameworks featuring a nanosized Ln6Cu24Na12 (Ln = Gd, Dy) cluster as a node have been obtained under microwave irradiation conditions through the reaction of H2ANMA (H2ANMA = l-alanine-N-monoacetic acid), Cu(NO3)2, and Ln(NO3)3 (Ln = Gd for 1, Dy for 2) with NaOH in deionized water. Investigations on the magnetic properties show that 1 exhibits ferrimagnetic behavior. The electrical conductivity measurements reveal that 1 behaves as a proton conductor.
