New structural insights into Fe <sub>2</sub> P <sub>2</sub> O <sub>7</sub> – unravelling an unresolved dispute and three reversible phase transitions Open
The debate in the literature whether the triclinic room-temperature crystal structure of iron(II) pyrophosphate (Fe 2 P 2 O 7 ) is centrosymmetric or not has been clearly resolved on the basis of new single-crystal X-ray intensity measurem…

Layer-By-Layer Magnetic Ordering via Idle Spins and the Optical Signature of Jahn–Teller Cr<sup>2+</sup> Ions in Sr<sub>2</sub>Cr(PO<sub>4</sub>)<sub>2</sub> Open
Blue/turquoise crystals of Sr2CrII(PO4)2 with prismatic shape and edge-length of up to 1 mm were obtained by a vapor-phase moderated solid-state reaction at 1273 K in sealed silica tubes. Its crystal structure was solved and refined from a…
