Dielectric response of novel one-dimensional hydrogen-bonded molecular crystal [4,6-dmpH][Hca]
摘要:
The frequency dependent dielectric response due to proton transfer is observed for the novel one-dimensional (1D) hydrogen-bonded co-crystal [4 6-dmpH][Hca] (4 6-dmp=4 6-dimethylpyrimidine ca=chloranilic acid) This response is only observed for an as-grown crystal in a metastable state with defects of hydrogen bonds The critical hydrogen-bond length and one-dimensionality might be deeply related to the metstable state (C) 2009 Elsevier B V All rights reserved
