The crystal structure of MnHg(SCN)4(L) (L=DMF) (MMTDMF) has been determined by X-ray crystallography and refined to conventional R value of 0.0395 (final R indices). The crystal system is monoclinic with space group P21/c and the unit cell contains four molecules (Z=4). Ambidentate SCN ion acts as a bridging ligand connecting the distorted tetrahedron and octahedron. N,N-Dimethylformamide (DMF) is coordinated to manganese atom through O(DMF) atom. Comparative analysis made with MnHg(SCN)4 (MMTC) revealed that the high nonlinearity of MMTC is not facilitated by the coordination of MMTC with DMF and the MMTDMF polymer is centrosymmetric leading to NLO inactivity. The results are rationalized by correlating the NLO properties with structure.
