In the title compound, [ZnCl(C2H7N3S)2]Cl, the ZnII ion is five‐coordinated in a distorted trigonal–bipyramidal arrangement, with the hydrazine N atoms located in the apical positions. The structure is stabilized by N—H?Cl hydrogen bonds, which involve both the Cl atoms and all the hydrogen donors, except for one of the two thioamide N atoms. A comparison of the geometry of thiosemicarbazide and S‐methylisothiosemicarbazide complexes with ZnII, CuII and NiII shows the pronounced influence of the hydrogen‐bond network on the coordination geometry of ZnII compounds. 相似文献

The title complex, [Cu(NO3)(C10H14N4O2S)(H2O)](NO3), is the first metal complex with a Schiff base derived from isothiosemicarbazide and pyridoxal (pyridoxal is 3‐hydroxy‐5‐hydroxymethyl‐2‐methylpyridine‐4‐carboxaldehyde). The CuII environment is a square pyramid, the equatorial plane of which is formed by the tridentate ONN‐coordinated isothiosemicarbazone and one water molecule, while the nitrate ligand is in the apical position. The existence of numerous strong intermolecular hydrogen bonds, and weak C—H?O and C—H?π interactions, leads to a three‐dimensional supramolecular structure. 相似文献

The structure of the title S‐alkylated isothiosemicarbazide, C12H15N3OS, was determined by single‐crystal diffractometry and compared with the structures of other compounds containing the S‐alkylthiosemicarbazide moiety. Such structures cluster into two groups, according to the different orientation of the –SR group with respect to the hydrazine N atom of the thiosemicarbazide. The cis arrangement is preferred by most molecules in the solid state, in spite of the possibility of intramolecular N—H?N interactions in the opposite orientation. 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 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

The title compound, methylene bis[bis(N,N‐diethylamino)carbeniumdithiocarboxylate] pentachlorooxorhenium, (C21H42N4S4)[ReCl5O], is the result of an unusual dimerization of the ligand bis(N,N‐diethylamino)carbeniumdithiocarboxylate [(Et2N)2C2S2] upon reaction with [ReOCl3(PPh3)2] in chloroform under reflux conditions. The compound was obtained as a dicationic moiety, with the molecular [ReOCl5]2− anion providing the charge compensation. The planes of the carbenium and thiocarboxylate moieties are nearly perpendicular to one another and the backbone C—C bond length in the N2CCS2 group is the same as a normal C—C single‐bond length. 相似文献

The title complex, chlorobis{ethyl N‐[(4‐methylanilino)thiocarbonyl]carbamate‐κS}copper(I), [CuCl(C11H14N2O2S)2], was synthesized by the reaction of cupric chloride with the corresponding thiourea derivative. The complex has imposed crystallographic m symmetry and the CuI coordination environment is trigonal planar, formed by two S atoms and one Cl atom. The formation of intramolecular hydrogen bonds promotes the stability of the complex. 相似文献

In the neutral title complex, trans‐bis(2,2′‐iminodiethanol‐N,O)bis(isothiocyanato)nickel(II), [Ni(NCS)2(C4H11NO2)2], the isothiocyanate ions and the diethanolamine molecules act as monodentate and bidentate ligands, respectively. The NiII ion exhibits a distorted octahedral configuration with crystallographically imposed inversion symmetry and NNCS—Ni—Namine and NNCS—Ni—Oamine bond angles of 88.78 (10) and 89.44 (10)°, respectively. The Ni—N bond distances are in the range 2.069 (3)–2.096 (2) Å. The molecules are linked by hydrogen bonds to form a three‐dimensional infinite lattice. 相似文献

The compounds 2‐{[(E)‐(4‐methoxyphenyl)methylene]amino}‐N‐(3‐methylphenyl)‐4,5,6,7‐tetrahydro‐1‐benzothiophene‐3‐carboxamide, C24H24N2O2S, (I), and N‐(4‐methylphenyl)‐2‐{[(E)‐(4‐methylphenyl)methylene]amino}‐4,5,6,7‐tetrahydro‐1‐benzothiophene‐3‐carboxamide, C24H24N2OS, (II), show antibacterial and antifungal activities. The m‐toluidine ring in (I) and the p‐toluidine ring in (II) are coplanar with their respective thiophene rings. In (I), an intermolecular C—H⋯O hydrogen bond is present, whereas (II) does not exhibit any significant intermolecular interactions. However, in both compounds, an intramolecular N—H⋯N hydrogen bond forms a pseudo‐six‐membered ring, thus locking the molecular conformation and eliminating conformational flexibility. 相似文献

A thiosemicarbazone derivative, 2‐acetylpyridine 4‐phenylthiosemicarbazone, was prepared and complexed to Lewis acids, Sn(CH3)2X2, X = Cl and Br. The products, [SnX(C14H13N4S)(CH3)2], were characterized by single‐crystal X‐ray diffraction, and IR, NMR and Mössbauer spectroscopies. They are isomorphous and crystallize in the monoclinic space group P21/n. The structure determination revealed discrete neutral complexes with the SnIV atom in a distorted octahedral coordination geometry, with the halogeno ligand and the thiosemicarbazone derivative in the equatorial plane and the methyl groups in axial positions. 相似文献

The title one‐dimensional chain nickel(II)–disulfide complex, [Ni(C14H8O4S2)(C5H5N)2(H2O)]n, has each NiII cation coordinated by two N atoms from two pyridine ligands, three carboxylate O atoms from two different dithiodibenzoate ligands and one O atom from a coordinated water molecule, in a distorted octahedral coordination geometry. Each dithiodibenzoate ion links two NiII cations through its carboxylate O atoms, making the structure polymeric. Hydrogen‐bond interactions between two shoulder‐to‐shoulder chains lead to the formation of a ladder‐like structure. 相似文献

catena‐Poly[[[tetraaquazinc(II)]‐μ‐4,4′‐bipyridine‐κ2N:N′] [[μ‐thiosulfato‐κ2O:S‐bis[(thiosulfato‐κS)zinc(II)]]‐di‐μ‐4,4′‐pyridine‐κ4N:N′] dihydrate], {[Zn(C10H8N2)(H2O)4][Zn2(S2O3)3(C10H8N2)2]·2H2O}n, is a polymeric zinc complex built up from thiosulfate‐containing anionic chains, where the Zn atom is tetrahedrally coordinated, and aqua‐containing cationic chains incorporating octahedrally coordinated Zn. In each type of chain, the 4,4′‐bipyridine units act as spacers, and the chains run along three non‐intersecting almost orthogonal directions in space. The profusion of hydrogen‐bond donors (all the H atoms of the water molecules) and acceptors (the thiosulfate O and S atoms) generates a very complex hydrogen‐bonding scheme. 相似文献

Pyridine fused with a furan ring (fupy), and its dimethyl derivative, have been used for the first time as ligands to synthesize potentially new Werner clathrates. The extended aromatic system of pyridine‐like ligands influences considerably the molecular structure of prepared nickel complexes. The molecular structure of tetrakis(furo[3,2‐c]pyridine)bis(isothiocyanato)nickel(II) tetrahydrofuran (THF) solvate, [Ni(NCS)2(C7H5NO)4]·C4H8O or [Ni(NCS)2(fupy)4]·THF, (I), reveals a `four‐blade propeller' arrangement of ligands, with the angles between the fupy planes and the basal octahedron plane spanning the range 38.7–55.3°. These angles are much larger (69.9–78.8°) in the centrosymmetric complex tetrakis(2,3‐dimethylfuro[3,2‐c]pyridine)bis(isothiocyanato)nickel(II) 6.6‐hydrate, [Ni(NCS)2(C9H9NO)4]·6.6H2O or [Ni(NCS)2(Me2fupy)4]·6.6H2O, (II), in which crystallographically imposed inversion symmetry is present. 相似文献

The title compound, [Mg(C5H4NOS)2(H2O)2]·C10H8N2O2S2, is a two‐component host–guest material. The 2,2′‐dithiobis(pyridine N‐oxide) molecule has crystallographic twofold symmetry. The metal complex lies on an inversion centre and associates via C—H?S interactions into chains which thread the 2,2′‐dithiobis(pyridine N‐oxide) lattice in perpendicular directions. Hydrogen bonds exist between the water molecules of the diaquamagnesium units and the N—O groups of the host lattice. 相似文献

The structure of the title compound, [Ni(ths)(bbip)(dmf)]·H2O [ths is thiosulfate, S2O3; bbip is 2,6‐bis(1H‐benzimidazol‐2‐yl)pyridine, C21H13N5; and dmf is dimethylformamide, C3H7NO], is monomeric, with the nickel ion octahedrally surrounded by an N,N′,N′′‐tridentate bbip molecule, an S,O‐bidentate ths molecule and an O‐monodentate dmf molecule. The H atoms of the hydration water molecule and the amino groups of bbip are involved in hydrogen bonding and determine a spatial organization of broad layers parallel to (001), which are connected by weak interactions. 相似文献

Gold(I) cyanide forms complexes with imidazolidine‐2‐thione (etu) and dimethylthiourea (dmtu) with the formula [Au2(CN)2L2], i.e. the title complexes dicyano‐1κC,2κC‐bis(imidazolidine‐2‐thione)‐1κS,2κS‐digold(I)(Au—Au), [Au2(CN)2(C3H6N2S)2], and dicyano‐1κ2C‐bis(N,N′‐dimethylthiourea)‐2κ2S‐digold(I)(Au—Au), [Au2(CN)2(C3H8N2S)2]. In the etu complex, two approximately linear (etu)AuCN groups are held together by a weak homopolar Au—Au bond [3.117 (1) Å], with a torsion angle of 61 (3)° between the two groups. In the dmtu complex, an approximately linear Au(dmtu)2 group is bound to an approximately linear Au(CN)2 group by a weak heteropolar Au—Au bond [3.091 (1) Å], with a torsion angle of 83 (5)° between the two groups. 相似文献
