Crystal structure determination on the mixed ligand complex [Ru(tpy)(L1)](ClO4)2 (tpy = 2,2′:6′,2″-terpyridine; L1 = 4′-(ferrocenylmethylaminomethylphenyl)terpyridine) shows the ferrocenyl group to be located as remotely as possible from the RuII centre. This may explain the fact that emission from the RuII centre is detectable even at room temperature in solution.

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.

The title compound, C20H18O3, was prepared in a one-step synthesis by intramolecular cyclization following the sigmatropic rearrangement of the allyl aryl ether intermediate. The room-temperature crystal structure determination reveals acisconformation of the ring annellation.
