  • Synthesis and Crystal Structure of Seven-Coordinate (<i>trans</i>-1,2-Cyclohexanediamine-<i>N</i>,<i>N</i>,<i>N</i>′,<i>N</i>′-tetraacetato)aquavanadate(III)

    日期:1991.8
    Potassium, sodium, and ammonium salts of [V(cydta)(H2O)]− complexes were prepared, where cydta denotes trans-1,2-cyclohexanediamine-N,N,N′,N′,-tetraacetate. Crystal structure analysis of Na[V(cydta)(H2O)]·5H2O revealed that the vanadium(III) atom adopts a capped trigonal-prism structure, a cydta acting as a sexidentate ligand and an aqua ligand occupying the capping position.

  • Carbonate binding to copper(ii) in solution: mixed-ligand complex formation and its application to the isolation and separation of the three isomers of [Cu(bpp)(H2O)][ClO4]2 [bpp = 2,6-bis(pyrrolidin-2-yl)pyridine]

    The binding of the carbonate anion to [Cu(meso-bpp)(H2O)]2+ and rac-[Cu(bpp)(H2O)]2+ [bpp = 2,6-bis(pyrrolidin-2-yl)pyridine] in aqueous solution has been investigated. Formation constants of the carbonato complexes [Cu(meso-bpp)(CO3)] and rac-[Cu(bpp)(CO3)] (1.02 × 103 M−1 and 1.77 × 103 M−1, respectively, μ = 0.70 M) have been calculated from spectrophotometric measurements. The formation of these Cu2+ complexes can also be used for an improved synthesis and an easy isolation of the three diastereoisomers of bpp. The mixture of [Cu(meso-bpp)(H2O)]2+ and rac-[Cu(bpp)(H2O)]2+ is separated by elution from SP Sephadex C-25, either as hydroxo or carbonato derivatives. rac-[Cu(bpp)(H2O)]2+ is then resolved into the enantiomers [Cu(S,S-bpp)(H2O)]2+ and [Cu(R,R-bpp)(H2O)]2+, again on SP Sephadex C-25, by means of L-(+)-tartrate as chiral eluent. The three stereoisomers, meso-bpp, (S,S)-bpp and (R,R)-bpp are liberated from the corresponding copper(II) complexes by ligand displacement using trans-1,2-diaminocyclohexane-N,N,N′,N′-tetraacetic acid (H4cdta). The structure of the meso isomer was solved by a single crystal X-ray analysis using the perchlorate salt [meso-bppH2][ClO4]2·2H2O.

    Abstract A general synthetic procedure for the preparation of Pd II and Pt II complexes with aminopolycarboxylate ligands is reported. These compounds are easily prepared from acetic acid solutions of MCl 2 and H 4 L (M = Pd or Pt; L = EDTA, PDTA or CDTA). Two different kinds of compounds can be isolated, [M (H 4 L) Cl 2 ] and (H 6 L) [MCl 4 ]. In the case of platinum compounds, both structures can
    摘要报道了制备具有氨基聚羧酸盐配体的Pd II和Pt II配合物的一般合成方法。这些化合物易于从MCl 2和H 4 L(M = Pd或Pt; L = EDTA,PDTA或CDTA)的乙酸溶液中制备。可以分离出两种不同的化合物,[M(H 4 L)Cl 2]和(H 6 L)[MCl 4]。对于铂化合物,可以使用电子光谱轻松区分两种结构。还已经从氯化合物的水溶液中分离出配合物[M(H 2 L)]。水溶液中的盐(H 6 L)[MCl 4]缓慢转化为配位L的相应络合物。对于铂化合物,已研究了该过程的动力学。
