The coordination chemistry of guanidines and guanidinates

The effect of solvent on the behaviour of the copper(II) complex of 1,4,7,10,13,16-hexaazacyclooctadecane (hexacyclen) has been investigated by cyclic voltammetry as well as visible absorption and EPR spectroscopy. Within a series of solvents with different coordination ability (pyridine, DMSO, DMF, water, acetone, acetonitrile) the Cu(II)/Cu(I) reduction potential (about –0.7 V on a mercury electrode and –1.1 V vs SCE on platinum), the d-d absorption band (15300 cm−1) and the values of gI and gII at -170°C (2.07 and 2.18, respectively) remain unchanged and indicate a stable octahedral CuN6 environment.

Stereochemistry of copper(II) complexes with hexacyclen in solution

EPR study on dichromate-dithizone interaction in nonaqueous medium

Formation of transient Pd(III) species was established in the course of PdCL42−-bilirubin (BR) reaction in basic-water medium. Using the EPR method the formation of an octahedral low-spin PdL.2H2O complex was proved exhibiting an anisotropic 2-component EPR spectrum (g1=2.007 and gu=1.998) and effective magnetic moment μeff = 1.7 BM.

Formation and Stabilization of Pd(Iii) in Presence of the Porphyrinato-Type Ligand Bilirubin

“Platinum blue” complex with a new type of bridging ligand

The laser flash photolysis of PtCl 2− 6 methanol solutions in the presence of l -proline and l -tryptophan revealed the formation of transient trivalent platinum complexes with these bioorganic ligands. Kinetic and spectroscopic parameters of these complexes were determined and continuous wave photolysis was studied to determine the final products of the photochemical reactions.
