✦ Synopsis

A new strontium oxoselenoantimonate(III), Sr 10 [Sb 7 O 13 (OH)] 2 [SbSe 3 ] 2 • 2H 2 O, has been hydrothermally synthesized and characterized by single crystal structure determination. It crystallizes in the monoclinic system, space group P2 1 /n, with a ‫؍‬ 11.4013(6) A s , b ‫؍‬ 18.417(1) A s , c ‫؍‬ 13.0568(7) A s , ‫,°)1(15.801؍‬ V ‫؍‬ 2599.9(2) A s 3 , measured at 223 K. In the structure [SbO 3 ] pyramids share oxygen atoms to form [Sb 7 O 13 (OH)] single branched six-rings that are interconnected by Sr-O bonds into layers with composition [Sr 5 Sb 7 O 13 (OH)]. The interlayer spaces are occupied by [SbSe 3 ] pyramids and isolated Se 2؊ anions. Both the [Sb 7 O 13 (OH)] single branched six-rings and the [SbSe 3 ] pyramids can be considered as building blocks of the known structure K 6 [Sb 12 O 18 ][SbSe 3 ] 2 • 6H 2 O.
