Two new lanthanum sulfates DySO{sub 4}(OH) 1 and Eu{sub 2}(SO{sub 4}){sub 3}(H{sub 2}O){sub 8} 2 have been hydrothermally synthesized. The colorless crystals were characterized by IR, TGA, ICP and XRD. The structure was determined by single-crystal X-ray diffraction. 1 crystallizes with monoclinic symmetry, space group P2(1)/n [a=7.995(4) A, b=10.945(5) A, c=8.164(4) A, {alpha}=90{sup o}, {beta}=93.619(6){sup o}, {gamma}=90{sup o}, V=713.0(5) A{sup 3}, Z=8]. It displays a three-dimensional framework, based on the novel Dy-O chains connected by the sulfate groups through helical chains. 2 crystallizes with monoclinic symmetry, space group C2/c, [a=13.5605(17) A, b=6.7676(8) A, c=18.318(2) A, {alpha}=90{sup o}, {beta}=102.265(2){sup o}, {gamma}=90{sup o}, V=1642.7 (4) A{sup 3}, Z=4]. Its layered framework is attained by the europium atoms connected by the sulfate groups arranged in a helical manner. - Graphical abstract: Two new lanthanum sulfates DySO{sub 4}(OH) 1 and Eu{sub 2} (SO{sub 4}){sub 3} (H{sub 2}O){sub 8} 2 have been hydrothermally synthesized.
