NITRILOTRIACETATE BRIDGED 3D-4F HETERONUCLEAR COMPLEX : SYNTHESIS AND CRYSTAL STRUCTURE OF {[GDCU(NTA)(H2O)6CL]CLO4·H 2O

Abstract

The heteronuclear gadolinium-copper complex was synthesized. Its crystal structure was determined by single-crystal diffraction. The crystal crystallizes in triclinic, space group P-1, a =0.8483(1) nm, b = 0.9642(2) nm, c = 1.2838(2) nm, α = 111.17(1)°, β = 93.52(1)°, γ = 100.89(1)°, Z=2, Dc = 2.335 g·cm-3. The complex appears as a zigzag 1D chain. Each gadolinium ion is coordinated by three carboxylic oxygen atoms and six oxygen atoms from H2O. Each copper ion is chelated by NTA with its nitrogen atom and three oxygen atoms of three carboxyl groups, and coordinated by a chlorine ion. The ClO4- is located between the chains as a counter ion.
