[{"from": "human", "value": "Create a molecule with the structure as the one described. The molecule is a chemical compound of barium and titanium. It is used as a dielectric material for ceramic capacitors and as a piezoelectric material for microphones and other transducers. It can also be found in thermistors and self-regulating electric heating systems, nonlinear optics, and thermal cameras. Barium is a metallic alkaline earth metal with the symbol Ba, and atomic number 56. It never occurs in nature in its pure form due to its reactivity with air, but combines with other chemicals such as sulfur or carbon and oxygen to form barium compounds that may be found as minerals.
