The crystals of the title compound, [Mg(C32H16N8)(H2O)]·2C3H9N, are built up from MgPc(H2O) [Pc is phthalocyaninate(2−)] and n‐propylamine molecules that interact via O—H⋯N hydrogen bonds. The MgPc(H2O) molecule is non‐planar. The central Mg atom is coordinated by the four equatorial isoindole N atoms of the Pc ring system and by the O atom of an axial water molecule. The Mg atom is displaced by 0.509 (1) Å from the N4 plane towards the water O atom. MgPc(H2O)·2(n‐propylamine) molecules related by the inversion centre are linked by N—H⋯O hydrogen bonds to form a dimeric aggregate. 相似文献

The title compound, [Cu(O2CCH=CHCH3)2(C5H5N)2(H2O)], crystallizes as a monomer, with the copper ion in a pentacoordinated square‐pyramidal environment, bisected by a twofold axis passing through the metal atom and the apex. The molecules organise in chains connected by hydrogen bonds running along the unique b axis. 相似文献

A new chromium(III)–phthalocyanine complex with the formula [Cr(C32H16N8)I], or CrPcI where Pc is phthalocyanate(2?), has been obtained by the reaction of pure Cr powder with phthalonitrile under a stream of iodine vapour. The five‐coordinate Cr atom is bonded to the four isoindole N atoms of the phthalocyaninate(2?) ligand and to one apical iodine ligand, and has a square‐pyramidal coordination geometry. The CrIII cation is significantly displaced [0.456 (2) Å] from the N4‐isoindole plane towards the I atom. The Cr—I bond is tilted 2.51 (4)° to the N4‐isoindole plane. 相似文献

The title mononuclear complex, [Yb(C5H7O2)3(C12H8N2)(H2O)], is a most uncommon carboxylate complex of a rare earth metal. Each YbIII ion is eightfold coordinated, being bonded to five O atoms of three dimethylacrylate groups, both N atoms of a phenanthroline and one O atom of a water molecule, giving a distorted square antiprismatic coordination polyhedron. 相似文献

The title compound, [Cu(C2H3O3)(C14H12N2)(H2O)]NO3, is the first example of a mixed copper glycolate compound with a diimine ligand. The copper(II) compound lies in a slightly distorted square‐pyramidal coordination environment with one water molecule coordinated in the apical position. The glycolate ligand binds to the Cu atom as a chelate through a carboxylate and the α‐OH O atom which, together with the N atoms of the substituted phenanthroline, constitute the base of the pyramid. 相似文献

In the title compound, [Ni(C2H3O)2(C3H4N2)4], the Ni atom is coordinated centrosymmetrically by four N and two O atoms in an octahedral coordination [Ni—N = 1.986 (3) and 2.054 (3) Å; Ni—O = 2.697 (3) Å]. The O atoms of the acetate anions form hydrogen bonds to adjacent imidazole moieties, with the free O atom forming a somewhat shorter bond [N?O = 2.679 (3) and 2.870 (4) Å]. The hydrogen bonds give rise to a two‐dimensional layer structure. 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 crystal structure of the title compound, [PtCl(CH3)(C18H33P)2], is isostructural with various platinum(II) and palladium(II) complexes containing two bulky tricyclohexylphosphine ligands in a trans orientation. The Pt atom resides on an inversion centre, resulting in a 50% statistical disorder in the chloro and methyl positions. The most significant geometrical parameters are Pt—P 2.3431 (8), Pt—Cl 2.440 (4) and Pt—C1 2.179 (13) Å, and P—Pt—P 180, P—Pt—Cl 89.15 (12) and 90.85 (12), and C—Pt—Cl 172.7 (5)°. The effective and Tolman cone angles for the tricyclohexylphosphine ligands were calculated as 160 and 162°, respectively. 相似文献

The asymmetric unit contains one complex cation, two tetrafluoroborate anions and one solvent water molecule, which is disordered over two sites (ratio of occupancies 0.70:0.30). 相似文献

Carbonyl O atoms from adjacent units complete the octahedral environment. 相似文献

Tris[2‐(benzoylamino)ethyl]amine [alternatively, N,N′,N′′‐(nitrilotriethyl)tribenzamide], C27H30N4O3, adopts a folded structure, forming a symmetrical cavity with an average depth of 7.3 Å and width ranging from 4.1–4.4 Å. The folded structure is a result of one intramolecular N—H?O hydrogen bond. A linear chain motif along the c axis best describes the extended intermolecular N—H?O hydrogen bonding. 相似文献

The title complex, [ZrCl2(C4H8O)2(C14H14N)2]·0.5C7H8, was prepared in an unusual manner by utilizing [Mg{N(CH2Ph)2}2] as a ligand transfer reagent. The Zr atom lies in a distorted octahedral environment where steric repulsion from the large dibenzylamino ligands leads to a widening of the N—Zr—N angle [99.95 (9)°] and corresponding compression of other angles [Cl—Zr—Cl 160.95 (3)° and O—Zr—O 78.22 (7)°]. This distortion is compared with those found in the previously determined structures of the dimethylamino and diethylamino analogues. 相似文献

In the structure of the title complex, [Cu(C2O4)(C10H9N3)(H2O)]·H2O, the CuII atom displays a square‐pyramidal geometry, being coordinated by two N atoms from the di‐2‐pyridylamine ligand, two O atoms from the oxalate group and one O atom of a water molecule. The complex molecules are linked to form a three‐dimensional supramolecular array by hydrogen‐bonding interactions between coordinated/uncoordinated water molecules and the uncoordinated oxalate O atoms of neighboring molecules. 相似文献

The square‐pyramidal Mg center in the title compound, [Mg(C32H16N8)(CH4O)], is five‐coordinate due to the formation of back‐to‐back π–π dimers that saturate the vacant apical site of the metal coordination sphere. Each complex is a member of a back‐to‐back and a face‐to‐face dimer; the latter are tethered by two strong O—H⋯N hydrogen bonds. The dimers form columns that likely determine the solid‐state packing. The phthalocyaninate ligands are essentially planar, with a slight `hat visor' conformation character. 相似文献

The title compound, meso‐C13H12O2S2, is in an anti conformation, with R and S configurations around the S atoms. The two O atoms are trans to each other, and the same applies for the two benzene rings. The phenylsulfinyl groups are nearly orthogonal to the central dithiomethane group, and the orientation of the two phenyl rings are determined by the interactions in which they are involved. The packing is built from molecular columns stabilized by weak C—H⋯O interactions. 相似文献

The title compound, [V(C2H6N)4], (I), has non‐crystallographic D2d molecular symmetry and contains an approximately tetrahedrally coordinated V atom with dimethylamido ligands. Each N atom features a nearly trigonal planar geometry. There are two independent molecules of (I) in the asymmetric unit. The results are compared with those previously reported for gas‐phase electron‐diffraction studies [Haaland, Rypdal, Volden & Andersen (1992). J. Chem. Soc. DaltonTrans. pp. 891–895]. 相似文献

Isomorphous triclinic forms of dichloro[phthalocyaninato(2−)]tin(IV), [Sn(C32H16N8)Cl2], and dichloro[phthalocyaninato(2−)]germanium(IV), [Sn(C32H16N8)Cl2], and a monoclinic form of the latter have been obtained from the reaction of pure tin and germanium powder, respectively, with phthalonitrile under a stream of ICl vapour. All three crystal structures consist of centrosymmetric [SnPcCl2] and [GePcCl2] [Pc is phthalocyaninate(2−)] molecules, which are separated but interacting. In the triclinic forms (Sn and Ge), the Pc macrocycles are not staggered but slipped, and in the monoclinic form (Ge), the molecules are additionally inclined. In both cases, the central Sn or Ge atom is six‐coordinated by the four isoindole N atoms of the Pc macrocyclic ligand and by two Cl atoms (located trans) into a tetragonal–bipyramidal structure. The arrangement of [SnPcCl2] and [GePcCl2] molecules in the crystal structure is determined mainly by intermolecular C—H⃛Cl, π–π and van der Waals interactions. 相似文献

The crystal structure of the first acesulfame–metal complex, namely tetraaquabis[6‐methyl‐1,2,3‐oxathiazin‐4(3H)‐onato 2,2‐dioxide‐κN]cobalt(II), [Co(C4H4NO4S)2(H2O)4], is reported. The CoII ion resides on a twofold axis and is coordinated by four aqua ligands defining the basal plane and by two monodentate acesulfamate ligands, via their ring N atoms, in the axial positions. Two intra‐ and three intermolecular hydrogen‐bonding interactions stabilize the crystal structure and form an infinite three‐dimensional lattice. 相似文献
