K2[Hg(SO3)2]·2.25H2O

M. Weil, S. O. Baumann and D. K. Breitinger

Synopsis: The crystal structure of K2[Hg(SO3)2]·2.25H2O contains two S-bonded sulfitomercurate anions, [Hg(SO3)2]2-, which are arranged pairwise and are surrounded by two K+ cations to give an anionic {K2[Hg(SO3)2]2}2- layer. The interlayer space is filled with the remaining cations and the water molecules.

Formula: K2[Hg(SO3)2]·2.25H2O

The novel arsenate Na4Co7-xAl2/3x(AsO4)6 (x = 1.37): crystal structure, charge-distribution and bond-valence-sum investigations

R. Marzouki, A. Guesmi and A. Driss

Synopsis: The title mixed hexaarsenate, Na4Co5.63Al0.91(AsO4)6, features a centrosymmetric three-dimensional framework composed of Co- and (Co,Al)-centred polyhedra and As-centred tetrahedra with tunnels running along [100] occupied by Na+ cations. Charge-distribution and bond-valence-sum calculations were used to support the structural model, and the experimental and validation results are discussed.

Formula: Na4Co5.63Al0.91(AsO4)6
