Two new complexes, [Cu(C2N3)2(dien)] (dien is diethylenetriamine, C4H13N3), (I), and [Cu(C2N3)(trien)](C2N3) (trien is triethylenetetramine, C6H18N4), (II), have been characterized by single‐crystal X‐ray diffraction. Both complexes display a distorted tetragonal–pyramidal geometry. In (I), the Cu atom is coordinated in the basal plane by three diethylenetriamine N atoms [Cu—N = 2.000 (2), 2.004 (2) and 2.025 (2) Å] and one terminal N atom [Cu—N = 1.974 (2) Å] from one monodentate dicyanamide group, and in the apical position by one terminal N atom [Cu—N = 2.280 (2) Å] from the other monodentate dicyanamide group. In (II), the Cu atom is surrounded by four triethylenetetramine N atoms [Cu—N = 2.012 (2), 2.014 (2), 2.019 (2) and 2.031 (2) Å in the basal plane] and a terminal N atom [Cu—N = 2.130 (2) Å in the apical site] from one monodentate dicyanamide group. The other dicyanamide anion is not directly coordinated to the metal atom. In both (I) and (II), hydrogen‐bond interactions between the uncoordinated terminal N atoms of two dicyanamide ions and the amine H atoms lead to the formation of three‐dimensional networks. 相似文献

In the crystal structure of [Cu(CF3SO3)(C2N3)(C8H7N5)2]·0.5C2H6O, the CuII atom adopts a distorted octahedral geometry, with the basal plane formed by two N atoms of one dipyrimidinylamine ligand, one N atom of the second pyrimidine ligand and a nitrile N atom of the dicyanamide anion [Cu—N = 1.972 (2)–2.021 (2) Å]. The apical positions are occupied by an N atom of the second ligand [Cu—N = 2.208 (2) Å], and an O atom of the trifluoromethanesulfonate anion [Cu—O = 2.747 (2) Å] at a semi‐coordination distance. Pairs of inversion‐related N—H⋯N hydrogen bonds of the so‐called Watson–Crick type, augmented by two C—H⋯N contacts, link adjacent complexes into an infinite one‐dimensional chain running in the [101] direction. 相似文献

In the title compound, [Au(C3H2N3S3)(C18H15P)3]·C3H7NO, the AuI atom has a distorted tetrahedral geometry consisting of one uncoordinated dimethylformamide molecule, one trithiocyanurate ligand and three PPh3 ligands. The S—Au distance is 2.909 (2) Å, and the P—Au distances fall in the range 2.400 (14)–2.4074 (13) Å. The S—Au—P angles are 92.81 (6), 99.17 (6) and 104.21 (5)°, and the P—Au—P angles are 114.46 (5), 119.04 (5) and 119.66 (5)°. 相似文献

The reaction of ClAuPPh3 and 1,1′‐biphenyl‐2,2′‐dithiol in the presence of trimethylbenzylammonium chloride and K2CO3 in a tetrahydrofuran/methanol solution gives the title complex, [Au2(C12H8S2)(C18H15P)2]. The molecule contains P—Au—S units which `cross' with torsion angles of ∼90° [P—Au—Au—P = 86.23 (5)° and S—Au—Au—S = 95.62 (5)°]. The intra‐ and intermolecular Au⋯Au distances [3.9064 (3) and 6.3797 (5) Å, respectively] are outside the range for typical Au⋯Au interactions. However, the Au atoms appear to be drawn together, leading to a significant bending of the P—Au—S angles [170.24 (5) and 169.52 (5)°]. 相似文献

Molecules of the title compound, [PdCl(C6H4NO2S)(PPh3)2]·C3H6O, exhibit a slight distortion from exact planarity at the Pd atom towards tetrahedral, with P—Pd—P and Cl—Pd—S angles of 174.98 (3) and 174.19 (3)°, respectively. The Pd—Cl and Pd—S bonds are, respectively, long [2.3550 (11) Å] and short [2.3020 (12) Å] for their types; the S—C bond is also very short [1.744 (4) Å]. The solvating acetone molecule is linked to one of the phosphine ligands by means of a C—H?O hydrogen bond. 相似文献

Molecules of 2‐(2‐nitrophenylaminocarbonyl)benzoic acid, C14H10N2O5, are linked into centrosymmetric R(8) dimers by a single O—H⋯O hydrogen bond [H⋯O = 1.78 Å, O⋯O = 2.623 (2) Å and O—H⋯O = 178°] and these dimers are linked into sheets by a single aromatic π–π stacking interaction. The isomeric compound 2‐(4‐nitrophenylaminocarbonyl)benzoic acid crystallizes in two polymorphic forms. In the orthorhombic form (space group P212121 with Z′ = 1, crystallized from ethanol), the molecules are linked into sheets of R(22) rings by a combination of one N—H⋯O hydrogen bond [H⋯O = 1.96 Å, N⋯O = 2.833 (3) Å and N—H⋯O = 171°] and one O—H⋯O hydrogen bond [H⋯O = 1.78 Å, O⋯O = 2.614 (3) Å and O—H⋯O = 173°]. In the monoclinic form (space group P21/n with Z′ = 2, crystallized from acetone), the molecules are linked by a combination of two N—H⋯O hydrogen bonds [H⋯O = 2.09 and 2.16 Å, N⋯O = 2.873 (4) and 2.902 (3) Å, and N—H⋯O = 147 and 141°] and two O—H⋯O hydrogen bonds [H⋯O = 1.84 and 1.83 Å, O⋯O = 2.664 (3) and 2.666 (3) Å, and O—H⋯O = 166 and 174°] into sheets of some complexity. These sheets are linked into a three‐dimensional framework by a single C—H⋯O hydrogen bond [H⋯O = 2.45 Å, C⋯O = 3.355 (4) Å and C—H⋯O = 160°]. 相似文献

The molecular structures of the title compounds, 2,4,6‐trichlorophenylisonitrile (IUPAC name: 2,4,6‐trichlorophenyl isocyanide), C7H2Cl3N, and 2,4,6‐trichlorobenzonitrile, C7H2Cl3N, are normal. The two structures are not isomorphous, but do contain similar two‐dimensional layers in which pairs of molecules are held together by pairs of Cl?CN [3.245 (3) Å] or Cl?NC [3.153 (2) Å] interactions. The two‐dimensional isomorphism is lost through different layer‐stacking modes. 相似文献

The title compound, [SnCl2(CH3)(C6H5)(C5H8N2)2], was obtained by reaction of dichloromethylphenyltin(IV) and 3,5‐dimethylpyrazole (dmpz) in chloroform, and was recrystallized from acetone. The structure consists of octahedral all‐trans [SnMePhCl2(dmpz)2] molecules, with the Sn atom coordinated to two C [Sn—C 2.127 (5) and 2.135 (4) Å], two Cl [Sn—Cl 2.5753 (8) Å] and two N atoms [Sn—N 2.357 (3) Å]. The dmpz ligands, bound to the metal through their unprotonated N atoms, form weak intra‐ and intermolecular hydrogen bonds with the Cl ligands via their NH groups, giving rise to a polymeric chain along the c axis. 相似文献

The bimetallic title complex, [CuFe(CN)5(C12H30N6O2)(NO)] or [Cu(L)Fe(CN)5(NO)] [where L is 1,8‐bis(2‐hydroxyethyl)‐1,3,6,8,10,13‐hexaazacyclotetradecane], has a one‐dimensional zigzag polymeric –Cu(L)–NC–Fe(NO)(CN)3–CN–Cu(L)– chain, in which the CuII and FeII centres are linked by two CN groups. In the complex, the CuII ion is coordinated by four N atoms from the L ligand [Cu—N(L) = 1.999 (2)–2.016 (2) Å] and two cyanide N atoms [Cu—N = 2.383 (2) and 2.902 (3) Å], and has an elongated octahedral geometry. The FeII centre is in a distorted octahedral environment, with Fe—N(nitroso) = 1.656 (2) Å and Fe—C(CN) = 1.938 (3)–1.948 (3) Å. The one‐dimensional zigzag chains are linked to form a three‐dimensional network via N—H⋯N and O—H⋯N hydrogen bonds. 相似文献

Molecules of 2‐amino‐4,6‐dimethoxypyrimidine, C6H9N3O2, (I), are linked by two N—H?N hydrogen bonds [H?N 2.23 and 2.50 Å, N?N 3.106 (2) and 3.261 (2) Å, and N—H?N 171 and 145°] into a chain of fused rings, where alternate rings are generated by centres of inversion and twofold rotation axes. Adjacent chains are linked by aromatic π–π‐stacking interactions to form a three‐dimensional framework. In 2‐benzylamino‐4,6‐bis(benzyloxy)pyrimidine, C25H23N3O2, (II), the molecules are linked into centrosymmetric R(8) dimers by paired N—H?N hydrogen bonds [H?N 2.13 Å, N?N 2.997 (2) Å and N—H?N 170°]. Molecules of 2‐amino‐4,6‐bis(N‐pyrrolidino)pyrimidine, C12H19N5, (III), are linked by two N—H?N hydrogen bonds [H?N 2.34 and 2.38 Å, N?N 3.186 (2) and 3.254 (2) Å, and N—H?N 163 and 170°] into a chain of fused rings similar to that in (I). 相似文献

2‐Amino‐5‐nitrothiazole crystallizes from solution in ethanol as a monosolvate, C3H3N3O2S·C2H6O, in which the thiazole component has a strongly polarized molecular–electronic structure. The thiazole molecules are linked into centrosymmetric dimers by paired N—H⋯N hydrogen bonds [H⋯N = 2.09 Å, N⋯N = 2.960 (6) Å and N—H⋯N = 169°], and these dimers are linked by the ethanol molecules, via a two‐centred N—H⋯O hydrogen bond [H⋯O = 1.98 Å, N⋯O = 2.838 (5) Å and N—H⋯O = 164°] and a planar asymmetric three‐centred O—H⋯(O)2 hydrogen bond [H⋯O = 2.07 and 2.53 Å, O⋯O = 2.900 (5) and 3.188 (5) Å, O—H⋯O = 169 and 136°, and O⋯H⋯O = 55°], into sheets built from alternating (8) and (38) rings.

In the title compound, [Pt(C18H15P)(C28H28P2S)](ClO4)2·C3H6O or [Pt(PPh3)(PSP)](ClO4)2·CH3COCH3, where PSP is the potentially tridentate chelate ligand bis(2‐diphenylphosphinoethyl) sulfide, all three donor groups of the PSP ligand are coordinated to the central Pt atom, with Pt—P = 2.310 (1) Å and Pt—S = 2.343 (1) Å. The fourth coordination site is occupied by the P donor of the triphenylphosphine ligand [Pt—P = 2.289 (1) Å]. The complex cation has exact mirror symmetry, with the S atom, the Pt atom and the P atom of the PPh3 ligand in the mirror plane. The Pt atom has a distorted square‐planar coordination geometry. A π–π interaction is present between the phenyl rings of the PPh3 ligand and the terminal –PPh2 group of the PSP chelate. 相似文献

The title complex, [Mo(C5H5)(C6H4FO)(C4H11Si)(NO)], is formed by reacting CpMo(NO)(CH2SiMe3)2, where Cp is cyclopentadienyl, with one equivalent of p‐FC6H4OH. The complex exhibits the expected piano‐stool molecular structure, with a linear nitrosyl ligand [Mo—N—O 168.2 (2)°] having Mo—N and N—O distances of 1.764 (2) and 1.207 (3) Å, respectively. The phenoxo Mo—O distance of 1.945 (2) Å is suggestive of some multiple‐bond character. 相似文献
