The title compound, [Ru(η5-C5H5){η6-C6H2(CH3)3NH2}]PF6, contains a sandwich complex with a mesitylamine unit which is significantly non-planar at theipso-carbon of the amino group due to repulsive electronic effects with Ru. Theipso-carbon deviates by 0.107 (3) Å from the least-squares plane of the remaining five benzene ring atoms, which show an r.m.s. deviation of 0.005 Å. N—H...F hydrogen-bonding interactions help to consolidate the crystal packing.

The structure of the title compound, trilead(II) bis[dihydroxidotetraoxidoiodate(VII)], was determined from a crystal twinned by non-merohedry with two twin domains present [twin fraction 0.73 (1):0.27 (1)]. It contains three Pb2+cations and two IO4(OH)23−anions in the asymmetric unit. Each of the Pb2+cations is surrounded by eight O atoms (cut-off value = 3.1 Å) in the form of a distorted polyhedron. The octahedral IO4(OH)23−anions are arranged in rows extending parallel to [021], forming a distorted hexagonal rod packing. The cations and anions are linked into a framework structure. Although H-atom positions could not be located, O...O distances suggest medium-strength hydrogen-bonding interactions between the IO4(OH)2octahedra, further consolidating the crystal packing.
