N2 - A new non-planar saddle shaped macrocyclic ligand 4,11-dihydro-5,7,12,14-tetramethyldibenzo[b,i][1,4,8,11]tetraazacyclotetradecine (H 2tmtaa) containing a six-coordinate germanium(IV) complex, Ge(tmtaa)(OOCH) 2 (1), in which two axial formate ligands are in the trans positions, has been synthesized. IR, UV, mass, NMR spectroscopic study and elemental analysis have been performed to characterize the complex. The single crystal X-ray diffraction analysis shows that in the solid state, molecules of 1 are connected through intermolecular hydrogen-bond weak interactions to form a one-dimensional supramolecular network. The temperature dependence of the electrical conductivity data (240-300 K) for 1 indicates a region of falling dσ/d(1/T), suggesting "semiconductor-like" charge transport in the stacking direction. The conductivity of 1 at room temperature is 6.1 × 10 -8 S/cm.
