Top view (a) and side elevation (b) of the 2D plane-like network of 1; the topological structure of 1(c), in which the Dy(III)2 dinuclear cluster and the TCBPA3− ligand act as the 6-connected and 3-connected vertices, respectively; one classical Chinese pane made of parallelograms (d), which has the same topology structure as 1.
