Disodium (2RS,3SR)-tartrate
The asymmetric unit of the anhydrous title compound, 2Na(+)·C(4)H(4)O(6) (2-), contains two sodium cations and one tartrate anion. Each sodium ion is six coordinate, with bonding to six O atoms from both the carboxyl-ate and hydroxyl groups of the anion. A three-dimensional coordination network is formed with sodium ions stacking in layers along the c-axis direction. This network is supported b...
متن کاملDisodium 4,4′-oxydibenzoate
The crystal structure of the title compound, 2Na(+)·C(14)H(8)O(5) (2-), consists of alternating layers of sodium cations and 4,4'-oxydibenzoate anions; the layers are perpendicular to the a axis, with the distance between the layers of cations (or anions) being half this axial length. The Na atoms are disordered over three sites [occupancies 0.775 (4), 0.781 (6) 0.444 (6)].
متن کاملCalcium disodium hexathiodiphosphate(IV) octahydrate
Single crystals of the title compound, CaNa(2)(P(2)S(6))·8H(2)O, were obtained by adding calcium hydroxide to an aqueous solution of Na(4)(P(2)S(6))·6H(2)O. The structure is isotypic with that of its strontium analogue and consists of one Ca(2+) cation, two Na(+) cations, one-half of a centrosymmetric (P(2)S(6))(4-) anion with staggered confirmation and four water mol-ecules in the asymmetric u...
متن کاملStrontium disodium hexathiodiphosphate(IV) octahydrate
The crystal structure of SrNa(2)(P(2)S(6))·8H(2)O is isotypic with that of its calcium analogue. The asymmetric unit consists of one Sr(2+) cation (2 symmetry), two Na(+) cations (2 and symmetry, respectively), one-half of a centrosymmetric (P(2)S(6))(4-) anion with a staggered confirmation and four water mol-ecules. The crystal structure is built up from layers of cations and anions extending ...
متن کاملDisodium tris(dioxidomolybdenum) bis(diarsenate)
The asymmetric unit of the title compound, Na(2)(MoO(2))(3)(As(2)O(7))(2), is composed of two cyclic MoAs(2)O(11) units and an MoO(6) corner-sharing octa-hedron. The anionic framework can be decomposed into two types of layers, viz. MoO(2)As(2)O(7) and Mo(2)As(2)O(14), which use mixed Mo-O-As and As-O-Mo bridges to achieve a new three-dimensional structure with two types of large channels in wh...
