“…The slight increase of χMT at high temperatures for 1 and 2 suggests the occurrence of a moderately weak ferromagnetic intramolecular interactions between the M III ions through the tris(oxalato)metalate(III) units [35][36][37]. The decrease in the value of the product χMT at very lower temperatures agrees with the occurrence of weak antiferromagnetic interactions between M III centres in both compounds [33,[38][39][40].…”

“…Furthermore, when compared to conventional mesostructured silica-based supports, the CPs ones have shown much higher activity and selectivity by providing good and regular interaction between metal species and organic reagents 22,23 . It has been found out that Ag-based CPs show high surface area and, as a result, a large number of reactions happen in presence of Ag-CP as catalyst [24][25][26][27] . Actually, in a number of cases, such reactions occur more pro ciently and with more selectivity, as compared to the reactions carried out in presence of other types of heterogeneous nanomaterials.…”

A highly efficient and stable heterogeneous coordination polymer (CP) was successfully prepared by hydrothermal combination of silver and 4,6-diamino-2-pyrimidinethiol. The prepared coordination polymer was characterized by FT-IR, XRD, TGA, SEM, EDX, X-ray mapping and Nitrogen adsorption-desorption analysis. The prepared Ag-CP exhibit excellent catalytic activity in multicomponent Hantzsch synthesis of polyhydroquinolines under mild reaction conditions in relatively short reaction times. The heterogeneity of the catalyst was confirmed by the hot filtration test; also, the catalyst was reused for at least four times under the optimized reaction conditions without any significant loss of its catalytic activity.

The double oxalates MI3[MIII(C2O4)3] possess rich crystallochemistry and can be used as precursors for various ceramic materials. The article discusses a case of Li3[Al(C2O4)3]. A series of previously unknown hydrates (Li3[Al(C2O4)3]·5.5H2O, Li3[Al(C2O4)3]·4H2O, Li3[Al(C2O4)3]·H2O) was found for this composition, their crystal structure and temperatures of mutual transformations determined. Transformation from Li3[Al(C2O4)3]·4H2O to Li3[Al(C2O4)3]·H2O was found to be accompanied by a change in the topology of the bonding network. Uniaxial negative thermal expansion was found for anhydrous Li3[Al(C2O4)3]. Thermal decomposition of Li3[Al(C2O4)3] was demonstrated to be a promising way to obtain precursors for aluminate ceramics.
