The synthesis and room-temperature single-crystal X-ray structure determination of the title compound are recorded. Crystals are monoclinic, P 21/c, a 14.43(2), b 18.39(1), c 23.64(3) Ǻ, β 123.16(7)°, Z = 4, isostructural with the recently described Fe3Ru5 analogue; R was 0.048 for 6892 'observed' data [I > 3σ(I)]. The cluster is one of the few containing separated carbide ligands within a polyhedral metal skeleton, consisting of an Ru5C square pyramid and an Ru6C octahedron sharing a triangular face, with two PPh2 groups bridging opposite Ru-Ru vectors in each polyhedron.

AbstractThis 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 single-crystal X-ray diffractometer allowed us to measure an extremely small crystal (i.e. 0.020 mm × 0.010 mm × 0.005 mm) and refine anisotropically all non-hydrogen atoms in the structure and provide a robust hydrogen-bond arrangement. Our new data confirm that natural lansfordite can be stable for several months at room temperature, in contrast with previous works, which reported that such a mineral could be stable only below 10°C.

AbstractThe crystal structure of NH4[C(CN)3] has been determined via X-ray single-crystal methods at 203(2) K corroborating earlier results. Additionally, the hydrogen positions have been determined and the Raman spectrum of the title compound recorded on single crystals. The spectroscopic results are compared to those for related compounds.
