Light pink crystal of composition [Co(4-CH2OH-5-CH3im)4](NO3)2 (where 4-CH2OH-5-CH3im denotes 4-hydroxymethyl-5-methylimidazole) were obtained from 2-propanol. The complex has been characterized by single-crystal X-ray as well as by electronic and vibrational spectroscopy. The immediate surrounding of the central ion is made up of four nitrogen atoms of the heterocyclic rings and two oxygen atoms of the hydroxymethyl group (CoN4O2 chromophore) The shape of the coordination polyhedron of the cobalt(II) ion is that of a slightly distorted octahedral. 相似文献

探讨了CaZr4-xTix(PO4)6(CZTP)离子置换与热膨胀的关系,随着X的增加,晶格参数a和c减小,热膨胀系数αa由负值变为正值,其平均的晶格膨胀系数大大增加,因而明显增大了CZTP系更的热膨胀系数。 相似文献

Summary The title polymer was prepared by the reaction of poly(4-formylstyrene) with 4-nitrophenylhydrazine. The polymer is amorphous and possesses a glass transition temperatureT
g=230 °C. It crosslinks both thermally and by UV-irradiation and forms dense networks when heated aboveT
g. All these properties make the polymer suitable for a stable poled system. However, a quite rapid thermal decay (bleaching) of the bound chromophore precludes the material from using in nonlinear optics. 相似文献

Raman spectra of (NH4)4H2(SeO4)3 protonic conductor were studied at room temperature using a 1064 nm - excited Fourier transform (FT) - Raman spectroscopy. A tentative assignment of the external and internal vibrations is proposed. 相似文献

A series of novel 1-(4-substitutedbenzoyl)-4-(4-chlorobenzhydryl)piperazine derivatives 5a-g was designed by a nucleophilic substitution reaction of 1-(4-chlorobenzhydryl)piperazine with various benzoyl chlorides and characterized by elemental analyses, IR and (1)H nuclear magnetic resonance spectra. Cytotoxicity of the compounds was demonstrated on cancer cell lines from liver (HUH7, FOCUS, MAHLAVU, HEPG2, HEP3B), breast (MCF7, BT20, T47D, CAMA-1), colon (HCT-116), gastric (KATO-3) and endometrial (MFE-296) cancer cell lines. Time-dependent cytotoxicity analysis of compound 5a indicated the long-term in situ stability of this compound. All compounds showed significant cell growth inhibitory activity on the selected cancer cell lines. 相似文献
