The turbostratically disordered misfit layer compound (SnSe){sub 1.15}VSe{sub 2} was synthesized and structurally characterized. Electrical transport measurements suggest this compound undergoes a charge or spin density wave (CDW or SDW) transition, which has not been observed in previous misfit layer compounds. The (SnSe){sub 1.15}VSe{sub 2} compound, created through the modulated elemental reactants technique, contains highly oriented intergrowths of SnSe bilayers and VSe{sub 2} structured Se–V–Se trilayers with abrupt interfaces between them perpendicular to the c-axis. X-ray diffraction data and transmission electron microscope images show that each constituent has in-plane crystallinity but that there is a random rotational disorder between the constituent layers. Temperature-dependent electrical resistivity data and Hall measurements are consistent with (SnSe){sub 1.15}VSe{sub 2} being a metal, however an abrupt increase in the resistivity occurs between 30 and 100 K. The carrier concentration decreases by approximately 1 carrier per vanadium atom during this temperature interval. - Graphical abstract: Turbostratically disordered (SnSe){sub 1.15}VSe{sub 2}. - Highlights: • New compound (SnSe){sub 1.15}VSe{sub 2}. • Turbostratic disorder. • Charge density wave at 100 K.
