catena‐Poly[benzyldecyldimethylammonium [plumbate(II)‐tri‐μ‐bromido]], {(C19H34N)[PbBr3]}n, crystallizes as an inorganic–organic hybrid following monoclinic space‐group symmetry P21/c. The structure consists of extended chains running along the [001] direction and built of [PbBr3] units. These inorganic chains are separated by interdigitated ammonium cations which form hydrophilic layers through weak C—H...Br interactions. The architecture is essentialy the same as found for n‐alkylbenzyldimethylammonium bromides.  相似文献

Self-assembly of a series of effective cation-templates with [Mo(W)/Cu/S]-based clusters was studied. Permanent templated products {(bppp)[MoOS3Cu3I3(4,4′-bipy)1.5]}n (1), {(bpbt)[MoOS3Cu3I3(4,4′-bipy)1.5]}n (2), {(bppp)[WOS3Cu3I3(4,4′-bipy)1.5]}n (3), and {(bpbt)[WOS3Cu3Br3(4,4′-bipy)1.5]}n (4) show 1D anionic zigzag pattern (bppp = 1,3-bis(pyridinium) propane, bpbt = 1,4-bis(pyridinium) butane). Compounds 14 have been characterized by single-crystal X-ray diffraction, elemental analysis, IR, UV–vis and thermogravimetric Analysis. The results may provide fascinating insights into template effects on the construction of the cluster-based coordination polymers and that coordination modes of compounds 3 and 4 have not been found in the reported one-dimensional zigzag coordination polymers.  相似文献

A one-dimensional (1-D) organic–inorganic hybrid compound {(H3O)[CuI(4,4′-bipy)]3[SiW12O40]} · 1.5H2O (1) has been synthesized from hydrothermal reaction of Keggin polyoxometalate, cupric nitrate and 4,4′-bipyridine (4,4′-bipy). Single crystal X-ray diffraction shows 1-D zigzag chains built up of saturated Keggin polyoxoanions and infinite [CuI(4,4′-bipy)] n n + units. Zipper-like arrangement of adjacent zigzag chains by hydrogen-bonding interactions leads to a 2-D layer and π–π interactions of 4,4′-bipy ligands from adjacent layers further result in the 3-D structure of 1. All Cu atoms in 1 are three-coordinated with “T-type” geometries, indicating they are univalent in the resultant compound. This result has further been confirmed by the absence of signal in the EPR spectrum of 1.  相似文献

Two cyanide-bridged heterometallic FeIII–MnII complexes with formula {[Mn(bipy)(H2O)]2[Fe(2-CH3im)(CN)5]2}n·nCH3OH·4nH2O (2) (bipy?=?2,2′-bipyridine) and {[Mn(MAC)][Fe(2-CH3im)(CN)5]}n·nDMF·3nH2O (3) (MAC?=?2,13-dimethyl-3,6,9,12,18-pentaazabicyclo-[12.3.1]octadeca-1(18),2,12,14,16-pentaene) have been successfully synthesized by assembling a newly designed pentacyanoiron(III) precursor [PPh4]2[Fe(CN)5(2-CH3im)]·2CH3OH (1) and two Mn(II) compounds containing bulky ancillary organic ligands as segments, and characterized by elemental analysis, infrared (IR) spectroscopy, and X-ray structure determination. X-ray diffraction analysis revealed one-dimensional (1D) ladder-like double or linear single infinite-chain structures for complex 2 and 3, respectively, indicating the obvious steric influence of the auxiliary ligand(s) on the structural type. Experimental and theoretical investigations on the magnetic properties of the complexes showed the antiferromagnetic coupling between the cyanide-bridged low-spin Fe(III) ion and high-spin Mn(II) ion.

The reaction of [Pt(CH2COMe)(Ph)(cod)] (cod=1,5‐cyclooctadiene) with (ArCH2NH2CH2‐C6H4COOH)+(PF6)? (Ar=4‐tBuC6H4 or 9‐anthryl) in the presence of cyclic oligoethers such as dibenzo[24]crown‐8 (DB24C8) and dicyclohexano[24]crown‐8 (DC24C8) produces {(ce)[ArCH2NH2CH2C6H4COOPt(Ph)(cod)]}+(PF6)? (ce=DB24C8 or DC24C8, Ar=4‐tBuC6H4 or 9‐anthryl) with interlocked structures. FABMS and NMR spectra of a solution of these compounds indicate that the Pt complexes with a secondary ammonium group and DB24C8 (or DC24C8) make up the axis and cyclic components, respectively. Temperature‐dependent 1H NMR spectra of a solution of {(DB24C8)[4‐tBuC6H4CH2NH2CH2‐C6H4COOPt(Ph)(cod)]}+(PF6)? ({(DB24C8)[ 4 ‐H]}+(PF6)?) show equilibration with free DB24C8 and the axis component. The addition of DB24C8 to a solution of {(DC24C8)[ 4 ‐H]}+(PF6)? causes partial exchange of the macrocyclic component of the interlocked molecules, giving a mixture of {(DC24C8)[ 4 ‐H]}+(PF6)?, {(DB24C8)[ 4 ‐H]}+(PF6)?, and free macrocyclic compounds. The reaction of 3,5‐Me2C6H3COCl with {(DB24C8)[ 4 ‐H]}+(PF6)? affords the organic rotaxane {(DB24C8)(4‐tBuC6H4CH2NH2CH2‐C6H4COOCOC6H3Me2‐3,5)}+(PF6)? through C? O bond formation between the aroyl group and the carboxylate ligand of the axis component. The addition of 2,2′‐bipyridine (bpy) to a solution of {(DB24C8)[ 4 ‐H]}+(PF6)? induces the degradation of the interlocked structure to form a complex with trigonal bipyramidal coordination, [Pt(Ph)(bpy)(cod)]+(PF6)?, whereas the reaction of bpy with [Pt(OCOC6H4Me‐4)(Ph)(cod)] produces the square‐planar complex [Pt(OCOC6H4Me‐4)(Ph)(bpy)].  相似文献

In order to search for new anionic architectures and develop useful organic–inorganic hybrid materials in halometallate systems, two new crystalline organic–inorganic hybrid compounds have been prepared, i.e. catena‐poly[triethyl(2‐hydroxyethyl)azanium [[bromidocadmate(II)]‐di‐μ‐bromido]], {(C8H20NO)[CdBr3]}n, (1), and catena‐poly[triethyl(2‐hydroxyethyl)azanium [[bromidomercurate(II)]‐di‐μ‐bromido]], {(C8H20NO)[HgBr3]}n, (2), and the structures determined by X‐ray diffraction analysis. The compounds are isostructural, crystallizing in the space group P21/n. The metal centres are five‐coordinated by bromide anions, giving a slightly distorted trigonal–bipyramidal geometry. The crystal structures consist of one‐dimensional edge‐sharing chains of MBr5 trigonal bipyramids, between which triethylcholine counter‐cations are intercalated. O—H...Br hydrogen‐bonding interactions are present between the cations and anions.  相似文献
