Methanol slightly pyridine slightly
WebHerein, we report three new guanidine-pyridine copper (II) complexes. The bis (chelate) complexes, 1 and 2, exhibit trigonal-bipyramidal coordination geometries with axial pyridine donors and equatorial guanidine and halide ligands. The bonds to the pyridine donors are slightly shorter than to the guanidine donors. Webwater (less then 0.5 mg/100 ml of water); slightly soluble in alcohol (1.29% w/w at 20 °C), more soluble in hot alcohol (100 g of saturated 96% alcoholic solution contains 28 g at 80 °C). Also one gram dissolves in 2.8 ml of ether, in 4.5 ml of chloroform, and in 1.5 ml of pyridine. The product is soluble in
