Abstract

C28H54CI2C112N4O28S2, triclinic, PI (no. 2), a = 8.6496(6) A, b = 9.6240(7) A, c = 13.7224(9) A, a = 100.865(5)°, β = 100.956(5)°, γ = 93.997(6)°, V = 1094.8 A, Ζ = 1, Rgf(F) = 0.058, wRntfF) = 0.175, T= 293 Κ. Source of material The solution of ethanolamine in 5 ml water was added slowly to 20 ml aqueous solution of 5 mmol sodium 3-formyl-4-hydroxy5-morpholinomethyl-benzenesulfonate. After stirring vigorously for 30 min, 10 mmol Cu(C104)2 · 6H2O was added to the resulting Schiff base. The mixture was refluxed for 1 h and cooled to room temperature. At first green square plate-shaped crystals were isolated from the precipitate, and then green needle-like crystals were obtained after a week by slowly evaporation of the solution at room temperature [1-4]. Experimental details The positions of the Η atoms of the disordered hydrate water could not be analyzed.
