“…Tetranuclear coordination complex [Li 2 Co 2 (piv) 6 (py) 2 ] (1) was synthesized by a reaction of lithium pivalate salt Li(piv), polymeric amorphous [Co(piv) 2 ] n and pyridine in equimolar ratio in a mixture of CH 3 CN and THF. This synthetic methodic is similar to that for previously reported [Li 2 M 2 (piv) 6 ] (M = Ni, Co, Zn) complexes [30][31][32]. The compound 1 crystallizes in triclinic space group P−1 (Fig.…”

“…Research on dinuclear copper compounds has been conducted since the 1950s [13][14][15], and they are still of great interest due to i.a. magnetic properties [16][17][18][19][20][21][22]. The spin exchange parameter (−2 J) for such compounds is most often in the range 200-600 cm −1 , which means antiferromagnetic coupling [23][24][25].…”

The first coordination compound of copper and tiglic acid named tetrakis(μ-tiglato)bis(tiglic acid)dicopper(II) was synthesized and crystallized from water solution. Its structure was determined and analyzed based on X-ray diffraction measurement. The paddle-wheel coordination system of the investigated compound was compared with other similar copper structures known in the literature. The Hirshfeld analysis was used for the detailed analysis of intermolecular interaction. The new compound was also characterized in terms of infrared absorption, thermal, and magnetic properties. The antiferromagnetic coupling of copper ions was found.

“…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.
