The dimer [(η5-C5Me5)Ru(C3B2Me5)RhCl]2 (2) reacts with 1,2-bis(diphenylphosphino)ethane (dppe) to give the triple-decker complex [(η5-C5Me5)Ru(C3B2Me5)Rh- (dppe)Cl] (3). Its constitution follows from NMR and MS data, and a single-crystal X-ray diffraction study.

Di-o-anisylcarbinol crystallizes in the triclinic system, space group [Formula: see text] with a = 7.50 (4), b = 10.89 (4), c = 7.98 (3) Å, α = 101.9 (1), β = 94.1 (1), γ = 94.6 (1)°, Z = 2, V = 633.11 Å3, Dc = 1.28 mg m−3, Dm = 1.26 (1) mg m−3, CuKα radiation, λ = 1.54178 Å, μ(CuKα) = 0.633 mm−1, F(000) = 260. The structure has been determined by direct methods using single crystal X-ray data and refined by least-squares to the final R factors R = 5.89% and Rw = 5.35%. The molecule has a twist-skewed conformation with the phenyl rings on nearly orthogonal planes. The crystal structure shows a hydrogen-bonded dimer and a peculiar arrangement of the methoxy and phenyl groups.

The crystal structure of the title compound, [Cr(OC(NH2)2)6] [Cr(CN)6].2(CH3)2SO.2CH3CH2OH, has been determined from a single-crystal X-ray diffraction study at 295(1) K. It was refined by least-squares methods to a residual of 0.039 for 4203 independent 'observed' reflections. Crystals are monoclinic, P21/n, a 17.449(6), b 10.315(4), c 11.726(3) �, β 102.51(2)�, Z 2. Both chromium atoms lie on crystallographic centres of symmetry. Cr-O(urea) are 1.960(2),1.962(2), 1.982(1) � and Cr-C(cyanide) 2.074(2), 2.080(2), 2.081(2) �; the geometries of the ligands and solvent molecules are correspondingly precise.

Abstract X-ray single crystal analysis of MnSO4·5H2O shows that the manganese atoms are octahedrally coordinated by oxygen atoms, four of which belong to water molecules and two to sulphate groups. A model derived from the crystal structure was fitted to the X-ray scattering intensities from aqueous MnSO4. Good agreement with experimental data is achieved using a model in which Mn(H2O)6-z(OSO3)z+2-2z interacts with about ten water molecules and each sulphate ion with about seven water molecules.

A single crystal X-ray diffraction study of the new compound [Rb([2.2.2]crypt)]2[Rb([18]crown−6)][HGe9]·4NH3 revealed the presence of the first protonated nine-atom germanide cluster [HGe9]3−. It forms from Rb4Ge9 in liquid ammonia, so that [Ge9]4− can be considered as the base and [HGe9]3− its formally conjugated acid. The H atom is attached to a germanium vertex atom of the basal square plane, as it is known for [RGe9]3− (R = C5H9, Mes, etc.) or [HE9]3− (E = Si, Sn). In addition, the proton could be located unambiguously in the Fourier difference map. [HGe9]3− also represents a nido cluster species with 22 cluster-bonding electrons, which can be considered the most stable structure for nine-atom cluster species for all group 14 elements.
