Bianchini, Robert J. published the artcileSynthesis and characterization of the three geometrical isomers of difluoro(1,3-propanediamine-N,N’-diacetato)chromate(III). Crystal structure of trans-Li[CrF2(1,3-pdda)].2H2O, Synthetic Route of 10517-44-9, the publication is Inorganic Chemistry (1986), 25(13), 2129-34, database is CAplus.
sym–cis-, unsym–cis-, And trans-Li[CrF2(pdda)] (H2ppda = 1,3-propanediamine-N,N‘-diacetic acid), unsym–cis-Li[CrL(pdda)] (H2L = oxalic and malonic acids) were prepared and characterized by UV-visible and 2H NMR spectroscopy. trans-Li[CrF2(pdda)].2H2O crystallizes in the orthorhombic space group Pnma with a 12.137(6), b 15.450(6), c 7.050(3) ?, Z = 4, and R = 0.053 for 1985 independent observed reflections collected at ambient temperature by a full-matrix least-squares refinement procedure. The complex has distorted-octahedral geometry around the Cr, with 2 F atoms trans to 1 another and a F-Cr-F angle of 176.67(9)¡ã. The Cr-F distances are 1.878(2) and 1.901(2) ?. The independent Cr-O and Cr-N distances are 1.992(2) and 2.060(2) ?, resp. The stability of trans-[CrF2(pdda)]– was established by 2H NMR and is attributed in part to the chair conformation of the ligand diamine hydrocarbon backbone. A new preparation scheme for incorporating deuterons into polyaminopoly(carboxylic acid) ligands is also reported.
