The crystal structure of the title compound, [Rb(C(12)H(24)O(6))](3)[Sb(7)]·4NH(3), fills the gap between the already known Zintl anion ammoniates {[Cs(18-crown-6)](3)Sb(7)}(2)·9NH(3) [Wiesler (2007 ▶). Dissertation, Universität Regensburg, Germany] and [K(18-crown-6)](3)Sb(7)·4NH(3) [Hanauer (2007 ▶). Dissertation, Universität Regensburg, Germany]. As in the two known compounds, the anti-mony ...
In the title compound, [Sb(C(6)H(5))(3)(C(8)H(4)F(3)O(3))(2)], the Sb atom lies on an inversion centre and exhibits a trigonal bipyramidal geometry with the axial positions occupied by the O atoms of two carboxyl-ate groups and the equatorial positions occupied by C atoms of the phenyl groups. Intra-molecular C-H⋯O hydrogen bonds stabilize the mol-ecular conformation. In the crystal structure, ...
On the Diophantine equations $d\sb 1x\sp 2+2\sp {2m}d\sb 2=y\sp n$ and $d\sb 1x\sp 2+d\sb 2=4y\sp n$
The title compound, (C(10)H(10)N(2))[Sb(2)(C(7)H(2)NO(5))(2)(OH)(2)(H(2)O)(2)]·2H(2)O, consists of a binuclear anion, a diprotonated 4,4'-bipyridinium cation and two uncoordinated water mol-ecules. Each Sb(III) atom is six-coordinated by one chelating 4-oxidopyridine-2,6-dicarboxyl-ate ligand, one water mol-ecule, one OH group and one bridging O atom from a neighboring carboxyl-ate group in a d...
