Tetrahedral Anion

The reactions of Zintl ions Sn94− formed in ethylenediamine solutions of K2Cs2Sn9 and Rb4Sn9 with elemental tellurium have been investigated. Addition of elemental tellurium to the filtrates of these solutions leads - depending on the reaction conditions - to four different products: Compounds K0.36(1)Cs3.64(1)[SnTe4] (1) and Rb4[SnTe4] (2) contain the tetrahedral anion [SnTe4]4−, and Cs4[Sn2Te7] (3) features the anion [Te2Sn(μ-Te)(μ-Te2)SnTe2]4−, whereas a novel Zintl anion [Sn4Te12]10− is present in compound K0.44(1)Cs9.56(1)[Sn4Te12] (4). Compounds 1, 2 and 4 have been structurally characterized by single-crystal X-ray diffraction

Tetrahedral Anion

The structure of the title salt, (C8H10NO)2[HgCl4], is isotypic with that of the cuprate(II) and cobaltate(II) analogues. The asymmetric unit contains one 4-acetylanilinium cation and one half of a tetrachloridomercurate(II) anion (point group symmetrym). The Hg—Cl distances are in the range 2.4308 (7)–2.5244 (11) Å and the Cl—Hg—Cl angles in the range of 104.66 (2)–122.94 (4)°, indicating a considerable distortion of the tetrahedral anion. In the crystal, cations are linked by an intermolecular N—H...O hydrogen-bonding interaction, leading to aC(8) chain motif with the chains extending parallel to thebaxis. There is also a π–π stacking interaction with a centroid-to-centroid distance of 3.735 (2) Å between neighbouring benzene rings along this direction. The anions lie between the chains and interact with the cations through intermolecular N—H...Cl hydrogen bonds, leading to the formation of a three-dimensional network structure.

Tetrahedral Anion

The structure of the title salt, (C8H10NO)2[CoCl4], is isotypic with the analogous cuprate(II) structure. The asymmetric unit contains one 4-acetylanilinium cation and one half of a tetrachloridocobaltate(II) anion for which the CoIIatom and two Cl−ligands lie on a mirror plane. The Co—Cl distances in the distorted tetrahedral anion range from 2.2519 (6) to 2.2954 (9) Å and the Cl—Co—Cl angles range from 106.53 (2) to 110.81 (4)°. In the crystal, cations are self-assembled by intermolecular N—H...O hydrogen-bonding interactions, leading to aC(8) chain motif with the chains running parallel to thebaxis. π–π stacking interactions between benzene rings, with a centroid-to-centroid distance of 3.709 Å, are also observed along this direction. The CoCl42−anions are sandwiched between the cationic chains and interact with each other through intermolecular N—H...Cl hydrogen-bonding interactions, forming a three-dimensional network structure.
