A New 3D Metal–Organic Framework Containing Chelidamic Acid with Unusual (3,6)-Connected Topology: Synthesis, Crystal Structure, and Optical Properties.

A new metal–organic framework [(LaL)·3H2O]n(L = chelidamic acid) with good optical properties was obtained through the hydrothermal reaction. It is the third three-dimensional framework constructed from chelidamic acid and presents a rare (3,6)-connected topology with Schläfli symbol (42.6)2(44.62.87.102). [ABSTRACT FROM AUTHOR]
