RESUMEN
(Acetonitrile-1κN)[µ-1H-benzimidazole-2(3H)-thione-1:2κ(2)S:S][1H-benzimidazole-2(3H)-thione-2κS]bis(µ-1,1-dioxo-1λ(6),2-benzothiazole-3-thiolato)-1:2κ(2)S(3):N;1:2κ(2)S(3):S(3)-dicopper(I)(Cu-Cu), [Cu(2)(C(7)H(4)NO(2)S(2))(2)(C(7)H(6)N(2)S)(2)(CH(3)CN)] or [Cu(2)(tsac)(2)(Sbim)(2)(CH(3)CN)] [tsac is thiosaccharinate and Sbim is 1H-benzimidazole-2(3H)-thione], (I), is a new copper(I) compound that consists of a triply bridged dinuclear Cu-Cu unit. In the complex molecule, two tsac anions and one neutral Sbim ligand bind the metals. One anion bridges via the endocyclic N and exocyclic S atoms (µ-S:N). The other anion and one of the mercaptobenzimidazole molecules bridge the metals through their exocyclic S atoms (µ-S:S). The second Sbim ligand coordinates in a monodentate fashion (κS) to one Cu atom, while an acetonitrile molecule coordinates to the other Cu atom. The Cu(I)-Cu(I) distance [2.6286 (6) Å] can be considered a strong 'cuprophilic' interaction. In the case of [µ-1H-benzimidazole-2(3H)-thione-1:2κ(2)S:S]bis[1H-benzimidazole-2(3H)-thione]-1κS;2κS-bis(µ-1,1-dioxo-1λ(6),2-benzothiazole-3-thiolato)-1:2κ(2)S(3):N;1:2κ(2)S(3):S(3)-dicopper(I)(Cu-Cu), [Cu(2)(C(7)H(4)NO(2)S(2))(2)(C(7)H(6)N(2)S)(3)] or [Cu(2)(tsac)(2)(Sbim)(3)], (II), the acetonitrile molecule is substituted by an additional Sbim ligand, which binds one Cu atom via the exocylic S atom. In this case, the Cu(I)-Cu(I) distance is 2.6068 (11) Å.
RESUMEN
The title compound, [Cu(2)(C(15)H(13)O(3))(4)(C(3)H(7)NO)(2)], is formed by the chelate coordination of four racemic fenoprofenate (fenoprofenate is 2,3-phenoxyphenyl propionate) anions and two dimethyl-formamide mol-ecules to two copper(II) ions, building a paddle-wheel dinuclear mol-ecule. The distorted square-pyramidal coordination of each Cu(II) atom is made up of four O atoms of the four fenoprofenate units and another O atom from a dimethyl-formamide mol-ecule. The two enanti-omeric forms of the fenoprofenate anions are present in the complex, in an optically inactive centrosymmetric arrangement.
RESUMEN
The centrosymmetric title compound, [Ag(C(7)H(4)NO(2)S(2))]n, consists of dinuclear units in which two thiosaccharinate anions each bridge two Ag atoms via an endocyclic N atom and an exocyclic S atom across a crystallographic centre of inversion midway between the Ag atoms. The dimeric units are connected via Ag-S(exo) interactions to create two-dimensional networks. The thiosaccharinate anions bridge in a mu3-S:S:N manner. The Ag...Ag distance can be considered a strong argentophilic interaction.
