Chemical preparation and x-ray characterization of a new compound hexaaqua-1,3-diammoniumpropane cobalt(II) nitrate, Co(H2O)6 [C3H12N2] (NO3)4 are reported. This mixed organo-mineral compound crystallizes in the orthorhombic system with Cmcm space group. The unit cell dimensions are: a = 10.795(7), b = 11.969(4), c = 14.685(5) Å, Z = 4 and V = 1897.5(12) Å3. The structure was solved using the direct method and refined to reliability R-factor of 0.036 using 2554 independent reflections. In this atomic arrangement the different species built a three-dimensional network. [ABSTRACT FROM AUTHOR]

A new adduct 4-benzyl piperidinium dihydrogenphosphate monophosphoric acid [C 12 H 16 NH 2 ] 2 (H 2 PO 4 ) 2 H 3 PO 4 , has been prepared and analyzed by X-ray diffraction. This adduct compound cristallizes in the monoclinic system, with the acentric space group P2 1 and the following unit-cell parameters: a = 13.103(3), b = 8.737(4), c = 13.620(3) Å, β = 92.38(2)°, Z = 2, and V = 1557.8(7) Å[3]. The crystal structure has been solved and refined to R = 0.059 and R (w) = 0.069 using 3306 independent reflections. Its structure can be described as inorganic layers of H 3 PO 4 and H 2 PO 4 - entities separated by organic molecules. In this atomic arrangement, H-bonds between the different species play an important role in the tridimensionnel network cohesion. Solid-state 13 C and 31 P MAS NMR spectroscopies are in agreement with the X-ray structure. Ab initio calculations allow the attribution of phosphorus and carbon signals to the independent crystallographic sites and to the various atoms of the organic groups. [ABSTRACT FROM AUTHOR]
