| Abstract: The complex,[Cu2(H2TTHA)(H2O)2]·6H2O has been synthesized in aqueous solution,where H6TTHA =triethylene tetraamine hexaacehc acid. Its crystal smicture has been determined with a fou-circle X-ray diffractometer to a final R value of 0.0654. The crystal ismonoclinic with space group P(21/n) The cell parameters ars as follows:a=0.7162(4),b= 1.3077(8),c= 1.5839(9)nm; β= 91.66(5)°,v=2, v=1.483(2)nm,dcalc= 1.7069 / cm3.In the crystal Cu(Ⅱ) ion is seven coordinated to form a squre pyramid |
