“…Although a great number of complexes and salts have been reported in the past, the description of structural information of lanthanide sulfates is still limited [1]. Actually, most of the known structures of the lanthanide sulfates are focused on hydrous sulfates, only few structures of anhydrous sulfates have been reported because of the difficulties in obtaining single-crystals for the structure determinations [2,3]. On the other hand, as precursors of lanthanide oxide, lanthanide nitrates have ever been extensively studied on the thermal decomposition [4][5][6][7][8][9][10].…”

“…The relevant La Á Á Á La distances are from 3.7798 (1) to 4.005 (1) A, and La-OLa bond angles are in the range of 64.6 (2)-94.32 (2)°.The whole crystal structure is of an infinite threedimensional framework(Fig. 2).In LaONO 3(2), all the oxygen atoms of nitrate group participate in coordination(Fig. 3), of which two (O1 and O1A) are, respectively, coordinated to three differ-ent lanthanum ions with La-O distances in the range of 2.650-2.771 A, and the last one (O2) is coordinated to two different lanthanum ions with average La-O distance of 2.578 A.…”

La(CH 3 SO 3 ) 3´2 H 2 O was prepared by the reaction of La 2 O 3 with CH 3 SO 3 H. According to the X-ray single crystal determination, the compound crystallizes with triclinic symmetry (P 1, Z = 2, a = 524.99(8), b = 1015.3(2), c = 1298.0(2) pm, a = 98.62(2)°, b = 91.12(2)°, c = 104.61(2)°, R all = 0.0405) and contains ninefold coordinate La 3+ ions. The coordination polyhedra are tricapped trigonal prisms which are connected by CH 3 SO 3 ± ions to double chains. These are linked via hydrogen bonding only. The thermal decomposition of La(CH 3 SO 3 ) 3´2 H 2 O was investigated by means of temperature dependent X-ray powder diffraction and DSC/TG/EGA methods. The compound dehydrates in a first step around 120°C to give the anhydrous methanesulfonate which decomposes finally yielding La 2 O 2 S 2 . According to the powder diffraction results the anhydrous methane sulfonate La(CH 3 SO 3 ) 3 crystallizes with a hexagonal structure (P6 3 /m, a = 998.26(6), c = 597.97(6) pm) which has been found for the respective perchlorate, hydrogensulfate, and amidosulfate previously. Synthese, Kristallstruktur und thermisches Verhalten von La(CH 3 SO 3 ) 3´2 H 2 OInhaltsu È bersicht. La(CH 3 SO 3 ) 3´2 H 2 O wurde durch Umsetzung von La 2 O 3 mit CH 3 SO 3 H erhalten. Nach den Ergebnissen der Ro È ntgenstrukturanalyse kristallisiert die Verbindung triklin (P 1, Z = 2, a = 524,99(8), b = 1015,3(2), c = 1298,0(2) pm, a = 98,62(2)°, b = 91,12(2)°, c = 104,61(2)°, R all = 0,0405) und entha È lt neunfach koordinierte La 3+ -Ionen. Die Koordinationspolyeder ko È nnen als dreifach bekappte trigonale Prismen gesehen werden, die u È ber CH 3 SO 3 ± -Ionen zu Doppelketten verbunden sind, welche ihrerseits nur von Wasserstoffbru È ckenbindungen zusammengehalten werden.Das thermische Verhalten von La(CH 3 SO 3 ) 3´2 H 2 O wurde mit Hilfe von DSC/TG/EGA-Messungen und temperaturabha È ngiger Pulverdiffraktometrie untersucht. Danach dehydratisiert die Verbindung zuna È chst bei etwa 120°C zu La(CH 3 SO 3 ) 3 , welches sich schlieûlich unter Bildung von La 2 O 2 S 2 zersetzt. Die wasserfreie Verbindung kristallisiert nach Ausweis der Pulveruntersuchungen hexagonal (P6 3 /m, a = 998,26(6), c = 597,97(6) pm) und ist isotyp zu La(ClO 4 ) 3 , La(HSO 4 ) 3 und La(NH 2 SO 3 ) 3 .
