In the title compound [systematic name: aqua(1,10‐phenanthroline‐κ2N,N′)(pyridine‐2,6‐dicarboxylato‐κ3O2,N,O6)manganese(II) monohydrate, [Mn(C7H3NO4)(C12H8N2)(H2O)]·H2O, the manganese(II) centre is surrounded by one bidentate phenanthroline ligand [Mn—N = 2.248 (3) and 2.278 (3) Å], one tridentate dipicolinate ligand [Mn—N = 2.179 (3) Å, and Mn—O = 2.237 (2) and 2.266 (2) Å] and one water molecule [Mn—O = 2.117 (3) Å], and it exhibits a strongly distorted octahedral geometry, with trans angles ranging from 144.12 (9) to 158.88 (11)°. Extensive intermolecular hydrogen‐bonding interactions involving coordinated and uncoordinated water molecules and the carboxyl O atoms of the dipicolinate ligand, as well as a stacking interaction involving the phenanthroline rings, are observed in the crystal structure. 相似文献

The title PtII complexes, viz. (2,2′‐bipyridine‐κ2N,N′)[(1R,2R)‐1,2‐diaminocyclohexane‐κ2N,N′]platinum(II) bis(hexafluorophosphate), [Pt(C6H14N2)(C10H8N2)](PF6)2, and [(1R,2R)‐1,2‐diaminocyclohexane‐κ2N,N′](1,10‐phenanthroline‐κ2N,N′)platinum(II) bis(hexafluorophosphate), [Pt(C6H14N2)(C12H8N2)](PF6)2, containing an aromatic α‐diimine and a non‐planar diaminocyclohexane, both form a ladder‐type structure, which is constructed via loose π–π stacking on the α‐diimine ligands and hydrogen bonding between the cyclic amines and the counter‐anions. In the former compound, there are two independent complex cations, both of which have a twofold axis through the Pt atom. 相似文献

Two different zinc sulfite compounds have been prepared through the decomposition of pyrosulfite–dithionite ions in aqueous solution, viz. a dimeric complex, di‐μ‐sulfito‐κ3O,O′:O′′;κ3O:O′,O′′‐bis[(4,4′‐dimethyl‐2,2′‐bipyridine‐κ2N,N′)zinc(II)] dihydrate, [Zn2(SO3)2(C12H12N2)2]·2H2O, (I), which was solved and refined from a twinned sample, and an extended polymer, poly[[aqua(1,10‐phenanthroline‐κ2N,N′)zinc(II)]‐μ3‐sulfito‐κ2O:O′:O′′‐zinc(II)‐μ3‐sulfito‐κ3O:O:O′], [Zn2(SO3)2(C12H10N2)(H2O)]n, (II). In (I), the dinuclear ZnII complex has a center of symmetry. The cation is five‐coordinate in a square‐pyramidal arrangement, the anion fulfilling a bridging chelating role. Compound (II) comprises two different zinc units, one being five‐coordinate (square pyramidal) and the other four‐coordinate (trigonal pyramidal), and two independent sulfite groups with different binding modes to the cationic centers. 相似文献

In title anhydrous catena‐poly[[trans‐bis(ethane‐1,2‐diamine‐κ2N,N′)copper(II)]‐μ‐dithionato‐κ2O:O′], [Cu(S2O6)(C2H8N2)2]n or [{H2N(CH2)2NH2}2Cu(O·O2SSO2·O)]∞, successive Cu atoms are bridged by a single doubly charged dithionate group, forming a one‐dimensional polymer with inversion centres at the metal atoms and the mid‐point of the S—S bond [Cu—O = 2.5744 (15) Å]. In title (hydrated) trans‐diaquabis(propane‐1,3‐diamine‐κ2N,N′)copper(II) dithionate, [Cu(C3H10N2)2(H2O)2](S2O6) or [{H2N(CH2)3NH2}2Cu(OH2)2](S2O6), both ions have imposed 2/m symmetry. The `axial' anion components are displaced by a pair of water ligands [Cu—O = 2.439 (3) Å], the shorter Cu—O distance being compensated by the lengthened Cu—N distance [2.0443 (18), cf. 2.0100 (13) and 2.0122 (16) Å]. 相似文献

Two new salts of the cation [CuI(dmp)2]+ (dmp is 2,9‐dimethyl‐1,10‐phenanthroline, C14H12N2), namely bis[bis(2,9‐dimethyl‐1,10‐phenanthroline‐κ2N,N′)copper(I)] bis(hexafluorophosphate) hemi[bis(4‐pyridylmethylidene)hydrazine] acetonitrile solvate, [Cu(C14H12N2)2]2(PF6)2·0.5C12H10N4·C2H3N or [Cu(dmp)2]2(PF6)2·0.5(bpmh)·CH3CN [bpmh is bis(4‐pyridylmethylidene)hydrazine, C12H10N4], (I), and bis(2,9‐dimethyl‐1,10‐phenanthroline‐κ2N,N′)copper(I) dicyanamide, [Cu(C14H12N2)2](C2N3) or [Cu(dmp)2][N(CN)2], (II), are reported. The Cu—N bond lengths and the distortion from idealized tetrahedral geometry of the dmp ligands are discussed and compared with related compounds. The bpmh molecule in (I) is π–π stacked with a dmp ligand at a distance of 3.4 Å, rather than coordinated to the metal atom. The molecule lies across an inversion center in the crystal. In (II), the normally coordinated dicyanamide molecule is present as an uncoordinated counter‐ion. 相似文献

In the title compounds, {2,2′‐[2,2‐dimethyl‐1,3‐propanediylbis(nitrilomethylidyne)]diphenolato‐κ4N,N′,O,O′}nickel(II), [Ni(C19H20N2O2)], and {2,2′‐[2,2‐dimethyl‐1,3‐propanediylbis(nitrilomethylidyne)]diphenolato‐κ4N,N′,O,O′}copper(II), [Cu(C19H20N2O2)], the NiII and CuII atoms are coordinated by two iminic N and two phenolic O atoms of the N,N′‐bis(salicylidene)‐2,2‐dimethyl‐1,3‐propanediaminate (SALPD2?, C17H16N2O22?) ligand. The geometry of the coordination sphere is planar in the case of the NiII complex and distorted towards tetrahedral for the CuII complex. Both complexes have a cis configuration imposed by the chelate ligand. The dihedral angles between the N/Ni/O and N/Cu/O coordination planes are 17.20 (6) and 35.13 (7)°, respectively. 相似文献

In each of the zinc(II) complexes bis(acetylacetonato‐κ2O,O′)(1,10‐phenanthroline‐κ2N,N′)zinc(II), [Zn(C5H7O2)2(C12H8N2)], (I), and bis(acetylacetonato‐κ2O,O′)(2,2′‐bipyridine‐κ2N,N′)zinc(II), [Zn(C5H7O2)2(C10H8N2)], (II), the metal center has a distorted octahedral coordination geometry. Compound (I) has crystallographically imposed twofold symmetry, with Z′ = 0.5. The presence of a rigid phenanthroline group precludes intramolecular hydrogen bonding, whereas the rather flexible bipyridyl ligand is twisted to form an intramolecular C—H...O interaction [the chelated bipyridyl ligand is nonplanar, with the pyridyl rings inclined at an angle of 13.4 (1)°]. The two metal complexes are linked by dissimilar C—H...O interactions into one‐dimensional chains. The present study demonstrates the distinct effects of two commonly used ligands, viz. 1,10‐phenanthroline and 2,2′‐bipyridine, on the structures of metal complexes and their assembly. 相似文献

Three cis nickel–dithiocyanate (SCN) complexes with different N,N′‐bidentate bases have been prepared and their crystal structures determined: bis(2,2′‐bipyridine‐N,N′)bis(thiocyan‐ato‐N)nickel(II), [Ni(SCN)2(C10H8N2)2], bis(1,10‐phenanthroline‐N,N′)bis(thiocyanato‐N)nickel(II), [Ni(SCN)2(C12H8N2)2], and bis(2,9‐dimethyl‐1,10‐phenanthroline‐N,N′)bis(thiocyanato‐N)nickel(II) monohydrate, [Ni(SCN)2(C12H8N2)2]·H2O.

Two new iron–oxo clusters, viz. di‐μ‐trifluoroacetato‐μ‐oxo‐bis[(2,2′‐bipyridine‐κ2N,N′)(trifluoroacetato‐κO)iron(III)], [Fe2O(CF3CO2)4(C10H8N2)2], and bis(2,2′‐bipyridine)di‐μ3‐oxo‐hexa‐μ‐trifluoroacetato‐bis(trifluoroacetato)tetrairon(III) trifluoroacetic acid solvate, [Fe4O2(CF3CO2)8(C10H8N2)2]·CF3CO2H, contain dinuclear and tetranuclear FeIII cores, respectively. The FeIII atoms are in distorted octahedral environments in both compounds and are linked by oxide and trifluoroacetate ions. The trifluoroacetate ions are either bridging (bidentate) or coordinated to the FeIII atoms via one O atom only. The fluorinated peripheries enhance the solubility of these compounds. Formal charges for all the Fe centers were assigned by summing valences of the chemical bonds to the FeIII atom. 相似文献

The title compound {systematic name: tetrakis(μ‐3,5‐dinitrobenzoato‐κ2O:O′)bis[(3,7‐dihydro‐1,3,7‐trimethyl‐1H‐purine‐2,6‐dione‐κO2)copper(II)]}, [Cu2(C7H3N2O6)4(C8H10N4O2)2], consists of paddle‐wheel dimeric tetrakis(μ‐3,5‐dinitrobenzoato‐κ2O:O′)dicopper(II) units with O‐coordinated caffeine molecules in both apical positions. The entire dimeric molecule lies on a tetragonal inversion axis, and thus one nitrobenzoate anion with one Cu atom in a special position belong to the independent part of the molecule. The caffeine ligand bonded to the Cu atom is disordered on a local twofold non‐crystallographic axis coincident with the axis. A π–π stacking interaction is observed between the caffeine rings and adjacent symmetry‐related benzene rings of the 3,5‐dinitrobenzoate anions. 相似文献

The title compound, [Pt(C6H10NO2)(C5H14N2)]2(SO4), crystallizes with two cations in the asymmetric unit. The two complex cations, which have a square‐planar PtII coordination, are chemically identical but differ slightly in the conformations of their amine groups. A neutral complex, viz. (2,2‐dimethyl‐1,3‐propanediamine‐κ2N,N′)bis(2‐piperidinecarboxylato‐κN)platinum(II), is shown to form in solution and to change rapidly into the title compound. 相似文献

The title compound, [Dy2(C8H7O2)6(C12H8N2)2], forms binuclear complexes, viz. di‐μ‐4‐methylbenzoato‐κ4O:O′‐bis[bis(4‐methylbenzoato‐κ2O,O′)(1,10‐phenanthroline‐κ2N,N′)dysprosium(III)] tetra‐μ‐4‐methylbenzoato‐κ8O:O′‐bis[(4‐methylbenzoato‐κ2O,O′)(1,10‐phenanthroline‐κ2N,N′)dysprosium(III)]. There are two independent binuclear complexes in the asymmetric unit, both of which are centrosymmetric. In one, the DyIII ions are linked by two bridging 4‐methylbenzoate groups, while in the other, the DyIII ions are linked by four bridging 4‐methylbenzoate groups. The remaining 4‐methylbenzoate groups and 1,10‐phenanthroline units coordinate to just one metal ion in bidentate modes. 相似文献

The structures of trans‐bis[2‐(aminomethyl)pyridine‐κ2N,N′]bis(saccharinato‐κN)zinc(II), [Zn(C7H4NO3S)2(C6H8N2)2], (I), and [2‐(aminoethyl)pyridine‐κ2N,N′]bis(saccharinato‐κN)zinc(II), [Zn(C7H4NO3S)2(C7H10N2)], (II), exhibit octa‐ and tetrahedrally coordinated ZnII atoms, respectively. The diamine ligands behave as N,N′‐bidentate ligands, while saccharinate (sac) is coordinated through the N atom. In (I), the complex lies about an inversion centre with the Zn atom disordered and displaced by 0.256 (2) Å from a centre of symmetry towards a sac N atom. The crystal structure of (I) is stabilized by N—H⋯O hydrogen bonds and the crystal packing of (II) is determined by hydrogen bonding as well as weak π–π stacking interactions between the sac ligands. 相似文献

Dichloro(4,4′‐dipentyl‐2,2′‐bipyridine‐κ2N,N′)platinum(II), [PtCl2(C20H28N2)], adopts a discrete π–π stacking structure, where the alkyl chains are located in a random manner. In contrast, dichloro(4,4′‐diheptyl‐2,2′‐bipyridine‐κ2N,N′)platinum(II), [PtCl2(C24H36N2)], forms a layer structure comprised of alkyl chain layers and paired coordination sites, as observed for analogous complexes with longer alkyl chains. 相似文献

The title complex, bis(acetylacetonato‐κ2O,O′)[N,N′‐bis(3‐hydroxy‐2‐oxidobenzaldimino)‐2‐methyl‐1,2‐propanediamine‐κ4N,O,O′,N′]uranium(IV) tetrahydrofuran solvate, [U(C18H18N2O4)(C5H7O2)2]·C4H8O, is a rare example of a uranium(IV) complex with a compartmental Schiff base. The U atom is located in the N2O2 inner site of the hexadentate N,N′‐bis(3‐hydroxy‐2‐oxidobenzaldimino)‐2‐methyl‐1,2‐propanediamine group and is bound also to the two O atoms of both acetylacetonate moieties, which results in a dodecahedral coordination environment. Centrosymmetric dimers are formed through intermolecular hydrogen bonds that link the terminal uncoordinated hydroxy groups to one another and to the O atoms of the acetylacetonate ligands. 相似文献

The title compound, [CoII(C10H8O6)(C10H8N2)(H2O)2]n, was obtained by the hydrothermal reaction of CoSO4 with benzene‐1,4‐dioxydiacetate [systematic name: p‐phenylenebis(oxyacetate)] and 4,4′‐bipyridine (4,4′‐bpy). The Co atom lies at an inversion center and the benzene‐1,4‐dioxydiacetate and 4,4′‐bipyridine moieties lie about other inversion centers. The benzene‐1,4‐dioxydiacetate ligands bridge the octahedral CoII coordination centers, forming a one‐dimensional zigzag chain. The chains are further bridged by 4,4′‐bpy ligands, forming a novel two‐dimensional supramolecular architecture. Hydrogen‐bonding interactions between the coordinated water molecules and the carboxylate O atoms lead to the formation of a three‐dimensional network structure. 相似文献

The three zinc sulfate complexes presented herein display three completely different coordination modes, viz triaqua(1,10‐phenanthroline‐N,N′)(sulfato‐O)zinc(II) hydrate, [Zn(SO4)(C12H8N2)(H2O)3]·H2O (octahedral, monomeric), bis(μ‐sulfato‐O:O′)bis[(2,9‐dimethyl‐1,10‐phenanthroline‐N,N′)zinc(II)], [Zn2(SO4)2(C14H12N2)2] (tetrahedral, dimeric), and catena‐poly[[diaqua(2,2′‐bipyridyl‐N,N′)zinc(II)]‐μ‐(sulfato‐O:O′)], [Zn(SO4)(C10H8N2)(H2O)2]n (octahedral, polymeric, twofold crystallographic symmetry). In the first, the sulfate is monodentate, while in the other two it acts as a bidentate bridge between two different Zn centers. There is a variety of sulfate S—O bond lengths, depending on the different coordination conditions and hydrogen‐bonding interactions. 相似文献
