Hydrothermal Syntheses and Characterizations of Thioarsenates [Fe(phen)₃][As₃S₆]·dien·7H₂O and [Mn₂(phen)₄(As₂S₅)]·phen·2H₂O: A New Coordination Mode of the As₂S₅⁴⁻Anion

Abstract

Novel hydrogen-bonded supramolecular thioarsenates [Fe(phen)(3)][As(3)S(6)] x dien x 7 H(2)O (1) and [Mn(2)(phen)(4)(As(2)S(5))] x phen x 2 H(2)O (2) (dien = diethylenetriamine, phen = 1,10-phenanthroline) were hydrothermally synthesized and characterized. The structure of 1 consists of [As(3)S(6)](3-)-H(2)O anionic layers and [Fe(phen)(3)](3+)-dien cationic layers assembled via O-H...S and O-H...N hydrogen-bonding interactions. The layers stack alternately and are parallel to each other to give a 3D network structure with channels accommodating unique branched water chains, which are anchored on the anionic and cationic layers via hydrogen bonds. In 2, the [As(2)S(5)](4-) anion acts as a tetradentate brigding ligand via four terminal S atoms to link two [Mn(phen)(2)](2+) cations, forming the neutral complex [Mn(2)(phen)(4)(As(2)S(5))]. This is a new coordination mode for the [As(2)S(5)](4-) ion. [Mn(2)(phen)(4)(As(2)S(5))], phen, and H(2)O form a 3D network structure via O-H...S, O-H...O, and pi-pi stacking interactions.

Room‐Temperature Synthesis of Three Compounds Featuring the [Ge4S10]4– Anion from a Water‐Soluble Thiogermanate Precursor

“…The two unique Mn 2+ cations in II are in a distorted octahedral MnN 4 OS coordination environment (Figure ). The Mn–S bond lengths [2.5470(17)–2.5471(18) Å] do not differ significantly from those that have been reported earlier [2.497(2)–2.542(2) Å] and match with the sum of the ionic radii (Mn 2+ : 0.67 Å; S 2– : 1.84 Å) The Mn–N bond lengths [2.247(5)–2.291(5) Å] are in agreement with values reported in the literature , , . The angles around Mn 2+ , which range between 72.29(19) and 168.21(14)° (Table S4), evidence severe distortion of the coordination geometry, but are still in the range of literature data , .…”

Synthesis, Crystal Structure and DNA-Binding Property of Mononuclear Mn(II) Complex

“…In the polyhedron of Mn atom, the N1 atom lies on the bottom and S1 atom situated at the apical station. The Mn-S1 bond length (2.5988 Å) is longer than those in the basal plane, which is similar to other manganese complexes 5 . DNA-binding property: The UV spectra have been widely employed to determine the binding characteristics of metal complexes and DNA 6 .…”

Review. Solvothermal Synthesis and Structure of Chalcogenidoarsenate Anions

“…In this and other relevant coordination polyhedra (i. e. ψ-ME 3 tetrahedra and ψ-ME 5 octahedra) of trivalent Group 15 elements M, use of the Greek letter ψ implies that one site is formally occupied by a non-bonded electron pair. The effective [26] [Sr(en) 4 ] 2 (As 3 Se 6 )Cl [29] [Fe(phen) 3 ]As 3 S 6 · dien · 7H 2 O [27], [Mn(dien) 2 ] 3 (As 3 Se 6 ) 2 [30] refs. [13,28] restriction to ψ-AsE 3 (E = S, Se) tetrahedra as the basic building units for the construction of oligomeric and polymeric anions leads to a striking paucity in the number of structural types adopted by the thio-and selenidoarsenates(III) in comparison to the analogous chalcogenidoantimonates(III) [9].…”
