The

[L
2
= N,N′-di(3-pyridyl)adipoamide;
1,4-H2pda = 1,4-phenylenediacetic acid] (5), are reported, which have been characterized by single crystal
X-ray diffraction. Complex 1 forms a looplike 1D chain,
whereas 2 and 4 show 3D frameworks with
a new self-catenated net with point symbol (65·8).
Complex 3 displays a 2D layer with the sql topology and 5 displays a rare 8T17 self-catenated
net. The dimensionality and structural types of 1–3 can be adjusted by varying the ligand isomerism of the dicarboxylate
ligands.
