Infrared spectra of Mn(NH3)2Zn(CN)4.2C6H6 andMn(ethylenediamine)Zn(CN)4.2C6H6 are reported. The spectral data suggest that these compounds are similar in structure toHofmann-Td-type and the en-Td-type clathrates,respectively. There is good evidence for H-bonding from ammoniaN–H to benzene as a to H-bond. 相似文献

IR spectra of Mn(trimethylenediamine)Zn(CN)42C6H6 and IR and Raman spectra of Zn(trimethylenediamine)Zn(CN)4_2C6H6 are reported. The spectral data suggest that the host frameworks of these compounds are similar to those of the tn-Td-type Cd(trimethylenediamine)M(CN)4_2benzene (M = Cd or Hg) and the chelated pn-Td-type Cd(propylenediamine)Cd(CN)4_1,2-dichloro-ethane clathrates, respectively. 相似文献

Three Hofmann-diaminododecane-type clathrates of the form M(1,12-diaminododecane) Ni(CN)4G (M = Co, Ni or Cd; G = benzene, naphthalene, anthracene, phenanthrene or biphenyl) have been prepared in powder form. The 1,12-diaminododecane molecules in the host lattice permit the inclusion of bulky guest molecules. The spectral features suggest that these compounds are similar in structure to the other Hofmann-diam-type clathrates. 相似文献

The torsional barriers and nonlinear optical properties for all phenylpyridine molecules were calculated by using Hartree-Fock
(HF) theory and Becke three-parameter functional (B3LYP) hybrid approaches within the density functional theory framework
with the 6-31++G(d, p) basis set, and via the GAUSSIAN 98W. The torsional barrier computations show that dihedral angle between
the two rings increases with the number of H-H vicinal interactions and torsional barriers with dihedral angles for 3-, 4-phenylpyridines
are too similar for both HF and B3LYP level calculations. Also, HOMO-LUMO energy gaps, polarizabilities, anisotropy of polarizabilities,
and static hyperpolarizabilities are calculated as a function of dihedral angle between benzene and pyridine rings. The study
reveals that the phenylpyridines show very low nonlinear optical properties. The calculated torsional barrier, equilibrium
dihedral angle and molecular dipole moment results for these molecules were compared with available experimental and other
results determining from different computational methods. 相似文献

IR spectra of Mn(en)M(CN)4·2C6H6 (M=Cd or Hg), and IR and Raman spectra of Cd(en)M(CN)4·2C6H6 (M=Cd or Hg) clathrates are reported. The spectral features suggest that the first two compounds are similar in structure to the later two Td-type clathrates. 相似文献

The host complex Cd(Cyclohexylamine)2Pd(CN)4 has been prepared in powder form. The spectral data suggest that the structure of this complex issimilar to those of the Hofmann-dma-type hosts. The sorption processes of thearomatic guests (benzene, toluene,o-, m-, p-xylene, naphthalene, 1,2-, 1,3-, 1,4-dichlorobenzene and 1,4-dibromobenzene) in this host have been examined at room temperature by gravimetric and spectroscopic measurements.The desorption of the benzene guest against time has been measured. The hoststructure changes on inclusion of the guests and recovers after liberations. Thehost complex has been suggested as sorbents for selective absorption. 相似文献

Two new benzene clathrates of the form Cd(4,4-bipyridyl)M(CN)4 · 2C6H6, (M=Cd or Hg) have been prepared in powder form. Their spectral data were compared with those of the corresponding host complexes and found to be consistent with the host structure found in Td-type clathrates. 相似文献

The host complexes M(Cyclopentylamine)2Ni(CN)4 (M=Co or Cd) havebeen prepared in powder form. The spectral data suggest that the structures of thesecompounds are similar to those of the Hofmann-dma-type hosts. The absorptionand the liberation processes of the aromatic guests (benzene, toluene, 1,2-, 1,3-,1,4-dichlorobenzene, 1,4-dibromobenzene o-, m-, p-xylene, naphthalene)in these hosts have been examined at room temperature by gravimetric and spectroscopicmeasurements. The desorption of the benzene guest against time has been measured. Thehost structures do not change on inclusion and liberation of the guests. The host compoundshave been suggested as sorbents for isomeric separations. 相似文献
