Study on crystal structure of a new cyclic trinuclear copper complex

A trinuclear copper substituted heterocyclic complex [Cu3(L-)3](ClO-4)3(L=2-hydroxy-1,3-propyldiamine) was prepared by the reaction of 2-hydroxy-1,3-propyldiamine with Cu(ClO4)2 6H2O and characterized by X-ray crystal structural analysis.The crystal crystallizes in the triclinic system,space group P-1 with unit cell parameters a=1.049 1(2) nm,b=1.080 8(2) nm,c=1.246 7(2) nm,α=74.451(3)°,β=70.635(3)°,γ=63.661(3)°,V=1.182 9(3) nm3,Z=4,R=0.058 7,wR=0.136 3.In the complex cation,every one of the three copper ions adopted a square coordination configuration with two nitrogen atoms and two bridging oxygen atoms from two neighboring ligand,a six-membered heterocyclic structure was formed by the three copper ions and the three bridging oxygen atoms respectively from the three ligands.
