Caesium tetrasilver dizinc nonathiocyanate, Cs[Ag4Zn2(SCN)9], forms a continuous structure, where the Ag atoms and the S atoms of the thiocyanate groups form chains which run along [101]. These chains are bonded together through the Cs and Zn atoms. It is not possible to distinguish between space groups P1 and P, but, if the latter space group is correct, the structure contains a thiocyanate group disordered across a centre of inversion. The structure is described in space group P, in which the Cs atom also lies on a centre of inversion. 相似文献

Calcium tetrathiocyanatodiargentate(I) dihydrate, Ca[Ag2(SCN)4]·2H2O, contains eight‐membered Ag4S4 rings bonded together through shared atoms to form layers parallel to (100). The thiocyanate groups link the layers to Ca–O chains running parallel to the c axis. The Ca atom is located on a twofold rotation axis parallel to b and is surrounded by four water molecules of crystallization and four thiocyanate N atoms in a distorted square antiprism. 相似文献

The title polymeric compound, catena‐poly[dipotassium [bis[μ‐N‐salicylidene‐β‐alaninato(2−)]‐κ4O,N,O′:O′′;κ4O′′:O,N,O′‐dicopper(II)]‐di‐μ‐isothiocyanato‐κ2N:S;κ2S:N], {K[Cu(NCS)(C10H9NO3)]}n, consists of [isothiocyanato(N‐salicylidene‐β‐alaninato)copper(II)]− anions connected through the two three‐atom thiocyanate (μ‐NCS) and the two anti,anti‐μ‐carboxylate bridges into infinite one‐dimensional polymeric anions, with coulombically interacting K+ counter‐ions with coordination number 7 constrained between the chains. The CuII atoms adopt a distorted tetragonal–bipyramidal coordination, with three donor atoms of the tridentate Schiff base and one N atom of the bridging μ‐NCS ligand in the basal plane. The first axial position is occupied by a thiocyanate S atom of a symmetry‐related μ‐NCS ligand at an apical distance of 2.9770 (8) Å, and the second position is occupied by an O atom of a bridging carboxylate group from an adjacent coordination unit at a distance of 2.639 (2) Å. 相似文献

From the 1:1 system of [Cu(dien)2](NO3)2 and K[Ag(CN)2] in water (dien is diethylenetriamine, C4H13N3), the novel compound catena‐poly[bis[[μ‐cyano‐1:2κ2C:N‐diethylenetriamine‐2κ3N‐copper(II)silver(I)]‐μ‐cyano‐1:2′κ2C:N] dicyanosilver(I) tricyanodisilver(I)], [CuAg(CN)2(dien)]2[Ag(CN)2][Ag2(CN)3], has been isolated. The structure is formed from positively charged [–Cu(dien)–NC–Ag–CN–]nn+ chains and two isolated centrosymmetric [Ag(CN)2]? and [Ag2(CN)3]? anions. In the cationic chains, the Cu atoms are linked by bridging dicyanoargentate groups, and the deformed square‐pyramidal coordination polyhedron of the CuII cation is formed from a tridentate chelate‐like bonded dien ligand and two N‐bonded bridging cyano groups. One of the bridging cyano groups occupies the apical (ap) position [mean Cu—Neq = 2.02 (2) Å, and Cu—Nap = 2.170 (3) Å; eq is equatorial]. Short argentophilic interactions in the range 3.16–3.30 Å are present in the crystal structure. 相似文献

In the title compound, catena‐poly[[bis(aniline‐N)cadmium(II)]‐di‐μ‐thiocyanato‐S:N;N:S], [Cd(SCN)2(C6H7N)2], the CdII atom lies on an inversion centre and is in a distorted octahedral geometry. The coordination sphere contains two thiocyanate (SCN) S atoms, two isothiocyanate (NCS) N atoms and two aniline N atoms. The six‐coordinated Cd atoms run parallel to the b axis and are doubly bridged with neighbouring Cd atoms by SCN and NCS ligands. Thus, this complex has a one‐dimensional coordination polymeric chain structure in which the aniline ligand is in the trans conformation. 相似文献

The novel PtII–dibenzo‐18‐crown‐6 (DB18C6) title complex, μ‐[tetrakis(thiocyanato‐S)platinum(II)]‐N:N′‐bis{[2,5,8,15,18,21‐hexaoxatricyclo[20.4.0.19,14]hexacosa‐1(22),9(14),10,12,23,25‐hexaene‐κ6O]potassium(I)}, [K(C20H24O6)]2[Pt(SCN)4], has been isolated and characterized by X‐ray diffraction analysis. The structure analysis shows that the complex displays a quasi‐one‐dimensional infinite chain of two [K(DB18C6)]+ complex cations and a [Pt(SCN)4]2? anion, bridged by K+?π interactions between adjacent [K(DB18C6)]+ units. 相似文献

The SCN– Ion as an Ambidentate Ligand – Synthesis and Crystal Structures of (Bu4N)4[Ag2Fe2(SCN)12] and (Et4N)2 [Ag2Fe(SCN)6] In (Bu4N)4[Ag2Fe2(SCN)12] · 2 CH3NO2 ( 1 ) and (Et4N)2[Ag2Fe(SCN)6] ( 2 ) the ambidentate SCN– anions link Ag+ with Fe3+ and Fe2+ centers, respectively.

In the title mononuclear cobalt complex, bis(2,6‐dimethyl‐1H,7H‐benzo[1,2‐d:4,5‐d′]diimidazole‐κN3)bis(thiocyanato‐κN)cobalt(II), [CoII(NCS)2(DMBDIZ)2] or [Co(NCS)2(C10H10N4)2], the cobalt(II) ion is coordinated to four N atoms, from two thiocyanate anions and two DMBDIZ ligands, in a distorted tetrahedral geometry. In the DMBDIZ ligand, the two imine N atoms are positioned cis with respect to one another. The crystal packing of the complex is dominated by both hydrogen bonding, involving two N—H?N and two N—H?S interactions, and aromatic π–π stacking. 相似文献

Introduction So far, considerable attention has been paid to mag-netic interaction between two different metal ions.1-3 As a potential bridging ligand, thiocyanate can coordinate to a harder metal center with N atom and softer ones with S atom at the same time, resulting in the formation of small ferromagnetic coupling.2 On the other hand, the Fe(III) atom is a good candidate as a hard acid and Ag(I) is a good candidate as a soft acid, so that the Fe(III) centers could be expected to conn… 相似文献

The new quaternary group V thiophosphate K4VP2S9 (tetrapotassium vanadium diphosphorus nonasulfide) was prepared by reacting a mixture of K2S3, VP, P4S3 and S. The crystal structure consists of discrete [VS(PS4)2]4− anions and K+ cations. The V4+ cation is in a fivefold coordination of S atoms which form a square‐pyramidal environment. Each VS5 group shares a common edge with two bidentate [PS4] tetrahedra, yielding the complete anion. The anions are stacked in the direction of the crystallographic b axis and are separated by the K+ ions. 相似文献

Both title compounds, bis[tris(2‐aminoethyl)amine]nickel(II) dichloride, [Ni(tren)2]Cl2, (I), and bis[tris(2‐aminoethyl)amine]nickel(II) tetrathiotungstate, [Ni(tren)2]WS4, (II), contain the [Ni(tren)2]2+ cation [tren is tris(2‐aminoethyl)amine, C6H18N4]. The tren molecule acts as a tridentate ligand around the central Ni atom, with the remaining primary amine group not bound to the central atom. In (I), Ni2+ is located on a centre of inversion surrounded by one crystallographically independent tren molecule. In the [Ni(tren)2]2+ cation of (II), the Ni atom is bound to two crystallographically independent tren molecules. The Ni atoms in the [Ni(tren)2]2+ complexes are in a distorted octahedral environment consisting of six N atoms from the chelating tren molecules. The counter‐ions are chloride anions in (I) and the tetrahedral [WS4]2? anion in (II). Hydrogen bonding is observed in both compounds. 相似文献
