Lattice dynamics and bond characteristics in SnCl4̇5H2O have been investigated using 35Cl nuclear quadrupole resonance (NQR). Two chemically inequivalent chlorine sites in SnCl4̇5H2O were distinguished from the temperature dependences of the NQR frequency and from the spin-lattice (T1Q) and spin-spin relaxation times (T2Q). The anomalous temperature dependence of the NQR frequency of one of the two sites was attributed to a thermal weakening of the crystal field from uncoordinated water molecules. In addition, high temperature activated molecular motion was observed.
