Structure determination of two metal-organic complexes from high-resolution synchotron powder diffraction dztz

The crystal structures of [1,2-bis(2,6-diisopropylphenylimino)acenaphthene-N,N′] carbonylchlororhodium(I) (1) and [N,N′-ethylene-nis(3-methylsalicylideneiminato)-O, N, N′, O′](tetrahydrofurfuryl)-cobalt(II) (2) have been determined from high-resolution synchrotron X-ray powder diffraction data. Compound 1 is the first neutral Rh complex, in contrast with findings in the literature, containing a bidentate nitrogen ligand, and compound 2 is the first three-dimensional structure of a (five-coordinated) tetrahydrofurfuryl-cobalt(III) complex. Grid-search and Rietveld refinement have been used to determine and refine the structures, respectively. Crystals of 1 are orthorhombic, space group Pbca, Z = 8, with cell parameters a = 21.729 (2), b = 27.376 (3), c = 11.580 (1) Å. Crystals of 2 are monoclinic, space group P2
