  SYNTHESIS AND ELECTRICAL PROPERTIES OF SOME NEW HETEROBIMETALLIC COORDINATION POLYMERS MPb(SCN)₄(M = Co, Ni) AND THEIR REACTION PRODUCTS WITH LEWIS BASES

  摘要：

  This paper describes a study of the electrical conducting behaviour of some new heterobimetallics of the composition MPb(SCN)(4) (M = Co(II), Ni(II)) and their Lewis base products of the forms MPb(SCN)(4)L-2 (L = pyridine (py) or triphenylphosphine (PPh3)) and [M(phen)(3)][Pb(SCN)(4)] (M = Co(II) or Ni(II); phen = 1,10-phenanthroline). The properties of these were investigated by using spectroscopic (IR, UV-Visible) methods as well as powder XRD and conductivity techniques. The IR spectra showed the bridging nature of SCN- in MPb(SCN)(4) and MPb(SCN)(4)(py)(2), both terminal and bridging SCN- in NiPb(SCN)(4)(PPh3)(2) and only terminal SCN- groups in [M(phen)(3)][Pb(SCN)(4)]. The magnetic data and electronic absorptions are also compatible with these proposed arrangements. Based on these studies. polymeric, monomeric and ionic structures have been proposed for these compounds. All of the compounds exhibited solid state sigma(rt) values in the 10 (12) to 10(-6) S cm(-1) range, and all showed semiconductivity from 303 to 363 K. A notable increase in conductivity, 10(2)-10(3) increase. at higher temperatures suggested some type of phase transition/packing equilibrium changes which produce effective M...S/Pb...S/S...S intermolecular interactions in NiPb(SCN)(4) and [M(phen)(3)][Pb(SCN)(4)].
