The growth morphology of MMTG (manganese mercury thiocyanate glycol monomethyl ether, MnHg(SCN) 4 (C 3 H 8 O 2 )) crystal was indexed according to the X‐ray powder diffraction spectroscopy. The density and Mohs hardness were determined at room temperature. The specific heat of the crystal is 458.6 J.mol ‐1 K ‐1 at 300 K. The thermal expansion coefficient (TEC) along the a, b and c axis is a 1 =6.89 × 10 ‐5 K ‐1 , a 2 =6.78 × 10 ‐5 K ‐1 and a 3 =2.08 × 10 ‐5 K ‐1 , respectively. The sameness and difference of the TECs are interpreted on the basis of crystal structure. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
