Bis(tetra-methyl-ammonium) oxalate monohydrate.

ABSTRACT: In the crystal structure of the title hydrated salt, 2C(4)H(12)N(+)·C(2)O(4) (2-)·H(2)O, the two independent cations, the anion and the water mol-ecule all lie on special positions of m site symmetry. In both cations, the mirror plane passes through the nitrogen atom and two methyl groups; in the anion, the mirror plane passes through two carbon and two oxygen atoms. The anions and water mol-ecules inter-act by O-H?O hydrogen bonding, forming a chain running along the b axis.

Bis(tetra-ethyl-ammonium) oxalate dihydrate.

Project description:The title compound, 2C(8)H(20)N(+)·C(2)O(4) (2-)·2H(2)O, synthesized by neutralizing H(2)C(2)O(4)·2H(2)O with (C(2)H(5))(4)NOH in a 1:2 molar ratio, is a deliquescent solid. The oxalate ion is nonplanar, with a dihedral angle between carboxyl-ate groups of 64.37?(2)°. O-H?O hydrogen bonds of moderate strength link the O atoms of the water mol-ecules and the oxalate ions into rings parallel to the c axis. The rings exhibit the graph-set motif R(4) (4)(12). In addition, there are weak C-H?O inter-actions in the crystal structure.

Bis(methyl-ammonium) tetra-sulfido-tungstate(VI).

Project description:The title compound, (CH(6)N)(2)[WS(4)], was synthesized by the reaction of ammonium tetra-sulfidotungstate(VI) with aqueous methyl-amine. The title compound is isotypic with the corresponding Mo analogue (CH(6)N)(2)[MoS(4)], and its structure consists of a slightly distorted tetra-hedral [WS(4)](2-) dianion and two crystallographically independent methyl-ammonium (MeNH(3)) cations, all of which are located on crystallographic mirror planes. The tetra-sulfidotungstate anions are linked to the organic cations via hydrogen-bonding inter-actions.

Bis(tetra-methyl-ammonium) tetra-chlorido-zincate(II), phase VI.

Project description:Phase VI of bis-(tetra-methyl-ammonium) tetra-chloro-zincate(II), (C(4)H(12)N)(2)[ZnCl(4)], contains three formula units per asymmetric unit. Several short C-H⋯Cl contacts [2.70 (3) and 2.72 (4) Å] are observed, but they are believed to participate only in van der Waals inter-actions. The crystal studied exhibited inversion twinning.

Tetra-methyl-ammonium aqua-trichlorido-oxalatostannate(IV) monohydrate.

Project description:The Sn(IV) atom in the title compound, [(CH(3))(4)N][Sn(C(2)O(4))Cl(3)(H(2)O)]·H(2)O, obtained from the reaction between SnCl(4) and [(CH(3))(4)N](2)C(2)O(4)·2H(2)O, is six-coordinated by three Cl atoms, an O atom of a water mol-ecule and two O atoms from an asymmetrically chelating oxalate anion. The environment around the Sn(IV) atom is distorted octa-hedral. The anions are connected by the lattice water mol-ecule through O-H?O hydrogen bonds, leading to a layered structure parallel to (010). The cations are located between these layers and besides Coulombic forces are connected to the anionic layers through weak C-H?O and C-H?Cl inter-actions.
