Abstract: | |
Colourless single crystals of [Eu(CH3COO)2(H2O)3]Cl are obtained at about 5°C from a solution of EuCl3 · 6 H2O in a mixture of acetone, tetrahydrofurane and acetanhydride (1:1:2) to which a small amount of water had been added. [Eu(CH3COO)2(H2O)3]Cl crystallizes in the monoclinic system, space group P21/n (No. 14), a = 786.19(5), b = 791.86(5), c = 1768.81(13) pm; β = 98.235(6)°, R = 0.025, Rw = 0.021, Z = 4. Eu3+ is in nine-coordinate surrounding of O2-, three of which belong to water molecules and six to acetate anions (two bidentate and two monodentate). Cationic chains of the composition [Eu(CH3COO)2(H2O)3]+ are formed through further connection via acetate-oxygen atoms. These chains are stacked hexagonally parallel [100] and held together by “lonesome” Cl- anions. The chloride ions are surrounded by 4+1 aquo ligands. | |
