Abstract:

A novel oxamidato-bridged CuⅡ-CoⅡ-CuⅡ trinuclear complex incorporating macrocyclic oxamide (macrocyclic oxamide=l,4,8,11-tetraazacyclotradecanne-2,3-dione),has been prepared and spectroscopically, structurally characterized. The complex crystallizes in monoclinic space group P2(l)/c, with a=0.771 72(4) nm, b=1.531 30(3) nm, c=1.472 98(7) nm, β=98.540(2)°, V=1.72137(13) nm3, Z=2,R=0.0843. The structure consists of trinuclear units and free water molecules and hydorgen bonds involving water molecules interlink the trinuclear units to form a unique one-dimensional chain.
