Abstract [en]

Insight into the control of interpenetrating coordination networks has been strategized by using linear dicarboxylates with different lengths. In this work, we rely on two roles of triethanolamine (H-bonding donations and cooperative stabilization of Zn-2 unit) to target the syntheses of two unique interpenetrating coordination polymers. The two representative compounds, [Zn-4(teaH(2))(2)(bdc)(3)]center dot 2(MeOH) (1; bdc(2-) = 1,4-benzenedicarboxylate and teaH(2) 2 = triethanolamine anion) and [Zn-2(teaH(2))(bpdc)(1.5)] (2; bpdc(2-) = biphenyl-4,4'-dicarboxylate), contain a well-defined Zn-2 unit as three-connected uninode but are assembled into two different topology nets. Compound 1 represents the first example of a two-fold interpenetrating 2D -> 3D 4.6(5)-crb supramolecular architecture constructed from a two-fold interpenetrating 4.8(2)-fes subnet, whereas compound 2 shows an unreported self-catenated 3D -> 3D 6(15) supramolecular network that can be made by H-bond cross-linking of an eight-fold 10(3)-ths subnet. The photoluminescent properties of the two compounds have also been investigated.
