“…Tetranuclear pivalates of the type [Li 2 M 2 (piv) 6 (py) 2 ] (M = Co, Ni, Zn) are cluster complexes that can be obtained by a simple procedure and feature a number of functional properties, such as magnetism and luminescence. − Because of the robust structure and fixed geometry of the carboxylate ligand, these complexes are excellent candidates as heterometallic building blocks for MOF synthesis. Only a handful of the corresponding coordination polymers have actually been synthesized, , and these are restricted to 1D or 2D nonporous structures, which limits their application to gas adsorption and capture.…”

The tetranuclear heterometallic complex [LiZn(piv)(py)] (1, where piv = pivalate and py = pyridine) has been successfully employed as a presynthesized node for the construction of four porous metal-organic frameworks (MOFs) [LiZn(R-bdc)(bpy)]·solv (2-R, R-bdc; R = H, Br, NH, NO) by reaction with 4,4'-bipyridine (bpy) and terephthalate anionic linkers. The [LiZn] node is retained in the products, representing a rare example of the rational step-by-step design of isoreticular MOFs based on complex heterometallic building units. The permanent porosity of the activated frameworks was confirmed by gas adsorption isotherm measurements (N, CO, CH). Three compounds, 2-H, 2-Br, and 2-NH (but not 2-NO), feature extensive hysteresis between the adsorption and desorption curves in the N isotherms at low pressures. The substituents R decorate the inner surface and also control the aperture of the channels, the volume of the micropores, and the overall surface area, thus affecting both the gas uptake and adsorption selectivity. The highest CO absorption at ambient conditions (105 cm·g or 21 wt % at 273 K and 1 bar for 2-NO) is above the average values for microporous MOFs. The photoluminescent properties of the prototypic 2-H as well as the corresponding host-guest compounds with various aromatic molecules (benzene, toluene, anisole, and nitrobenzene) were systematically investigated. We discovered a rather complex pattern in the emission response of this material depending on the wavelength of excitation as well as the nature of the guest molecules. On the basis of the crystal structure of 2-H, a mechanism for these luminescent properties is proposed and discussed.

“…are considered as candidates to this role. In spite of many presently described complexes with anions of halogen-containing carboxylic acids [16][17][18] and intensive investigation of the carboxylate complexes as a whole [19][20][21][22][23][24][25][26], they are rarely considered as fragments of supramolecular systems based on halogen bonds. From the point of view of the electronic structure, the iodoacetate anion is especially interesting in the context of hydrogen bonds.…”

The reactions of [Cu 2 (IOAc) 4 (H 2 O) 2 ] with 3-bromopyridine and 4-ethylpyridine in acetone afford heteroligand complexes [Cu 2 (IOAc) 4 (3-BrPy) 2 ] (I) and [Cu 2 (IOAc) 4 (4-EtPy) 2 ] (II). Their structures are determined by X-ray diffraction analysis (CIF files CCDC nos. 1945900 (I) and 1945901 (II)). Specific noncovalent interactions I•••I and Br•••I leading to the formation of supramolecular polymers are observed in the crystal structure of complex I. The energies of the contacts are determined using quantum chemical methods.

“…In fact, only Fe, Cu and Sb complexes are known, as well as lithium salt . This apparent lack of interest is unexpected, considering that electronic structure of IOAc – anion is rather favorable for XB formation (and overall great number of carboxylate complexes).…”
