Abstract
Abstract The nuclear quadrupole resonance of chlorine in sodium tetrachloroiodate(III) dihydrate was observed between 77 and 365°K. Four resonance lines were observed indicating the presence of four kinds of crystallographically nonequivalent chlorine atoms in the crystals. Unlike other resonance lines, the lowest-frequency line shows a positive temperature coefficient of resonance frequency. X-Ray powder patterns indicate the isomorphism of this complex with sodium tetrachloroaurate(III) dihydrate. With the aid of X-ray crystal analysis of the latter compound, it is concluded that the resonance line showing the positive temperature coefficient is attributable to chlorine atoms involved in hydrogen bonding.
