摘要

Neutral and ionic complexes of organic-inorganic hybrids having general formulas of [M(C_nH_(2n+1_-im)_2Cl_2](C_nH_(2n+1)-im, represents N-alkyl substituted imidazoles; n = 10, 12 and 18 for M = Pd(II); n = 12 and 18 for M = Cu(II) and Zn(II)) and [M(C_nH_(2n+1_-im)_4][NO_3]_2(for M = Cu(II), Zn(II), n= 10, 12, 14, 16 and 18), have been investigated. Three neutral compounds, [Pd(C_(12)H_(25)-im)_2Cl_2], [Cu(C_(12)H_(25)-im)_2Cl_2] and [Zn(C_(18)H_(37)-im)_2Cl_2] and one ionic compound [Cu(C_(12_H_(25)-im)_4][NO_3]_2 were structurally determined by single crystal X-ray diffraction. Among them, the Zn(II) compound is tetrahedral and the others are square planar. Among the neutral compounds synthesized, only the zinc compound with n = 18 exhibits liquid crystalline behavior upon cooling from isotropic liquid. All the ionic Zn(II) compounds exhibit SmA mesophases, except that with n = 10, which is a room-temperature ionic liquid. Ionic Cu(II) compounds exhibit a highly ordered lamellar mesophase.
