Crystal structure of bis(aquasamarium) trisuccinate, Sm2(H2O)2(C4H4O4)3

Abstract

C 12 H 16 O 14 Sm 2 ,triclinic, P1 (no. 2), a =7.7690(4) Å, b =8.0818(4) Å, c =14.1673(7) Å, a =96.908(1)°, b =96.977(1)°, g =103.362(1)°, V =848.9 Å 3 , Z =2, Source of materialAmixture of SmCl 3 · 6H2O(1.00 mmol, 0.38 g), succinic acid (1.00 mmol, 0.12 g), NaOH (2.00 mmol, 0.08 g) and H 2O( 10.0 ml) was heated in a23mlTeflon-lined stainless steel reactor at 443 Kfor 48 h. The colorless column-like crystals were filtered off and washed with water and acetone (yield 32 %based on Sm). Discussion
