ML type complexes of an olefin terminated 5H-dipyrrin ligand can be subjected to twofold ring closing metathesis to give bis(dipyrrinato)copper(ii) and bis(dipyrrinato)zinc(ii) [2]catenates. Demetalation of the copper(ii) [2]catenate with KCN/NH·HO gave the corresponding bis(dipyrrin) [2]catenand. The boron difluoride complex of this bis(dipyrrin) was obtained as the first fluorescent F-BODIPY [2]catenane.

The title compound, [Cu(C4F7O2)2(C12H8N2)(H2O)], is mononuclear and contains a penta-coordinated Cu(II) ion. The geometry of Cu(II) ion can be described as distorted square-pyramidal with two O atoms of two butano-ate anions and two N atoms of the o-phenanthroline ligand occupying the basal plane, and a water O atom located at the axial position. In the crystal, C-H⋯(O,F) and O-H⋯(O,F) hydrogen bonds and π-π inter-actions [centroid-to-centroid distance 3.

The title compound, [Mn2(C6H5COC6H4COO)2(C10H8N2)4](ClO4)2, comprises a centrosymmetric binuclear cation and two perchlorate anions. In the complex cation, two Mn(II) atoms are bridged by two O atoms of two different 2-benzoyl-benzoate ligands, each Mn(II) atom being further coordinated by two 2,2'-bi-pyridine (bipy) ligands in a distorted octa-hedral environment. Within the binuclear mol-ecule, the Mn⋯Mn separation is 4.

However, there are some limitations of metal-based ligands for the treatment of cancer due to their toxic effects. In the present study, a novel bimetallic Cu(II) complex, [Cu2(μ-(C6H5)2CHCOO)3 (bipy)2)](ClO4), has firstly been synthesized and characterized by FT-IR, and X-ray crystallography.

We have synthesized ethyl (2E)-3-amino-2-({[(4-benzoyl-1,5-diphenyl-1H-pyrazol-3-yl)carbonyl]amino}carbonothioyl)but-2-enoate (2) by the reaction of 4-benzoyl-1,5-diphenyl-1H-pyrazole-3-carbonyl chloride (1), ammonium thiocyanate and ethyl 3-aminobut-2-enoate and then characterized by elemental analyses, IR, Raman, (1)H NMR, (13)C NMR and X-ray diffraction methods. The experimental and theoretical vibrational spectra of 2 were investigated. The experimental FT-IR (4000-400 cm(-1)) and Laser-Raman spectra (4000-100 cm(-1)) of the molecule in the solid phase were recorded.

These complexes are readily prepared from the reaction between Au(THT)Cl (THT = tetrahydrothiophene) and the corresponding xanthate ligands as the potassium salts. The two xanthate complexes are characterized by (1)H NMR, IR, mass spectrometry, elemental analysis, and UV-vis techniques.

Compound 1 contains two gold atoms homobridged by the anionic dithiophosphonate ligand, forming an eight-membered ring complex in a chair form. After the reaction of 1 with diphosphine ligands, the dinuclear open-ring complexes Au(2)(dppm)(dtp)(2) (2), Au(2)(dppe)(dtp)(2) (3), Au(2)(dppp)(dtp)(2) (4), Au(2)(dppb)(dtp)(2) (5) were formed (dppm = diphenylphosphinomethane; dppe = diphenylphosphinoethane; dppp = diphenylphosphinopropane; dppb = diphenylphosphinobutane).
