structure structure (solids and liquids) D 2000 -003Synthesis, Structure, and Properties of Compounds in the NaHSO 4 -CsHSO 4 System. Part 1. Crystal Structures of Cs 2 Na(HSO 4 ) 3 and CsNa 3 (HSO 4 ) 3 .-Single crystals of the title compounds are grown from aqueous solutions of Cs 2 CO 3 , Na 2 CO 3 , and H 2 SO 4 . CsNa 2 (HSO 4 ) 3 crystallizes in the cubic space group P2 1 3 with Z = 4 and Cs 2 Na(HSO 4 ) 3 crystallizes in the hexagonal space group P6 3 /m with Z = 2. Both structures contain a single, crystallographically distinct, asymmetric hydrogen bond and unique, three-membered (HSO 4 ) 3 rings. The geometric match between NaO 6 and the sulfate rings suggests that the sodium polyhedra may serve to template the (HSO 4 ) 3 unit. -(CHISHOLM, CALUM R.
