Abstract: Heterodinuclear complexes [Cr(bpy)2(H2O)(μ-O)Ta(C2O4)3]2·3.5H2O (1) and [H2(terpy)][Cr(terpy)(C2O4)(μ-O)Ta(C2O4)3]·0.5H2C2O4·2.5H2O (2) (bpy = 2,2′-bipyridine; terpy = 2,2′:6′,2′′-terpyridine) have been synthesised through a reaction of a tris(oxalate)oxotantalate(V) anion and a complex chromium(III) cation with corresponding aromatic N-donor ligands. These are… read more here.

DOI: 10.1107/s2056989019011095
Abstract: The title compound is the first crystal structure of the pyrrolo[1,2-c]oxazole ring system. In the crystal, weak C—H⋯O and C—H⋯F hydrogen bonds link the molecules into [001] chains and π–π stacking interactions consolidate the structure. read more here.

DOI: 10.1180/minmag.2016.080.152
Abstract: Abstract This study presents the first crystal-structure determination of natural MgCO3·5H2O, mineral lansfordite, in comparison with previous structural works performed on synthetic analogues. A new prototype singlecrystal X-ray diffractometer allowed us to measure an extremely… read more here.
