摘要：Large high-optical-quality single crystals of diaqua(thiocyanato)manganese mercury-N,N-dimethylacetamide (MMTWD) were grown from solutions by the slow temperature reduction method. The morphology of the crystal was indexed. Raman spectroscopy of MMTWD crystals was performed at room temperature. The thermal expansion coefficients (TECs) along the a and c axes were measured to be alpha(1) = 2.26 x 10(-5) and alpha(3) = 5.91 x 10(-5) /K, respectively. All the TECs are positive and are interpreted on the basis of crystal structure. The thermal decomposition was characterized by differential scanning calorimetry.
