Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
An exploratory study of the hydrothermal chemistry of vanadium in HF solutions has resulted in the preparation of four new vanadium (III) fluorides with chainlike structural motifs. [NH4]2[VF5] (1) and [C2N2H10][VF5] (2) feature infinite chains of trans corner-sharing VF4F2/2 octahedra, [C4N2H6][VF5]·H2O (3) has cis corner-sharing [VF4F2/2]∞ chains, and [C10N2H8][VF3] (4) has trans corner-sharing [VF2F2/2]∞ chains bridged into sheets by the 4,4‘-bipy linker. All four compounds exhibit antiferromagnetic behavior.
