Bis(2,2'-bipyridine)(pyridine-2-carboxylate)ruthenium(II) hexafluorophosphate at 173K

K. Lashgari, R. Norrestam and B. Åkermark

Synopsis: The structure of the title compound, bis(2,2'-bipyridine-N,N')(pyridine-2-carboxylate-N,O)ruthenium( II) hexafluorophosphate, determined at 173K, is in good agreement with the structure determined at 295K [Canty et al. (1997). Inorg. Chim. Acta, 255, 117-123]. The coordination formed by five N atoms and one O atom around the RuII ion deviates substantially from octahedral symmetry. The relatively large thermal parameters of the F atoms in the PF6 anion can be assumed as being due to substantial rigid group vibrations.

Formula: [Ru(C6H4O2)(C10H8N2)2]PF6

Commensurately modulated 1/4 and 1/5 phases of deuterated betaine calcium chloride dihydrate: a neutron structural study

O. Hernandez, J.-M. Kiat, A. Cousson, W. Paulus, J. M. Ezpeleta and F. J. Zúñiga

Synopsis: The structures of the commensurate 1/4 and 1/5 phases of the displacively modulated compound D-BCCD [deuterated betaine (trimethylammonioacetate) calcium chloride dihydrate, i.e. (CD3)3NCD2COOCaCl2(D2O)2 or CaCl2.C5D11NO2.2D2O] have been determined by single-crystal neutron diffraction at 100 and 68 K, respectively. The structural model of the 1/4 phase is found to be quite different from that obtained previously from X-ray diffraction data of the hydrogenated compound.

Formula: CaCl2C5D11NO22D2O at 100 and 68 K
