Competitive milling was successfully employed to determine the relative affinity of Cu(ii) ions towards selected l-amino acids (Asn, Gln, His, Phe, Pro, and Trp). Described process opens a simple route towards mixed coordination compounds.

AbstractReaction of Mn(NCS)2with pyrazole leads to the formation of three compounds with the compositions Mn(NCS)2(pyrazole)4(1), [Mn(NCS)2]2(pyrazole)6(2) and Mn(NCS)2(pyrazole)2(3). Compound1, already reported in the literature, consists of discrete complexes, in which the Mn(II) cations are octahedrally coordinated by four pyrazole ligands and two terminally N-bonded thiocyanate anions. In compound2each of the two Mn(II) cations are coordinated octahedrally by three pyrazole ligands and one terminal as well as two bridging thiocyanate anions, which link the metal cations into dimers. In compound3also octahedrally coordinated Mn(II) cations are present but they are linked into chainsviacentrosymmetric pairs ofμ-1,3-bridging thiocyanate anions. Upon heating compound1loses the pyrazole co-ligands stepwise and is transformed into the chain compound3viathe dimer2that is formed as an intermediate. Magnetic measurements on compounds2and3reveal dominating antiferromagnetic interactions, as already observed for 1D Mn(NCS)2coordination compounds with pyridine based co-ligands.
