Shaping structural properties of double perovskite Sr2FeMoO6 and metal-organic perovskite [C(NH2)3]Cu[HCOO]3 under high pressure

Perovskite structures can be easily adapted not only by inorganic compositions, but by organic groups as well. In this proposal we aim to explore the pressure behaviour of double perovskite Sr2FeMoO6 and metal-organic perovskite ACuX3, in which A = [C(NH2)3] is guanidinium and X is the formate [HCOO]. Our aim is twice: evaluate the spin crossover in Sr2FeMoO6 up 50 GPa via powder XRD, and the pressure tuning of [C(NH2)3] and [HCOO] groups within ACuX3 system via single-crystal XRD.
