N2 - Rational synthesis of a series of new heterometallic MOFs was carried out by the judicious choice of the corresponding pivalate complexes [Li 2 M 2 (piv) 6 (py) 2 ] (M = Zn 2+ , Co 2+ , piv - = pivalate anion and py = pyridine) as a source of secondary building units, {LiM(O 2 CR) 3 } and an organic tricarboxylate linker as a node defining the dimensionality of the framework by the orientation of the carboxylic group in or out of the central aromatic ring plane. Thus the trimesate (btc 3- ) linker results in 3D srs topology frameworks with intersecting systems or isolated channels, and 1,3,5-benzenetribenzoate (btb 3- ) results in layered hcb isostructural compounds additionally stabilized with H-π interactions between the layers. The layered compounds demonstrate a permanent porosity with a BET surface area of up to 688 m 2 ·g -1 with the possibility of selective gas adsorption (CO 2 over N 2 and CH 4 ). Zn-Based coordination polymers show notable color changes and drastic (up to 30 times) quenching of luminescence upon inclusion of different nitroaromatics.
