Materials characterization. Powder X-Ray Diffraction (PXRD) data were collected on the Empyrean diffractometer (PANalytical) employed with Ni-filtered Cu Kα radiation (40 kV, 40 mA) using Bragg-Brentano geometry and Si zero-background holder. The Single Crystal X-ray Diffraction (SCXRD) data for the reported complexes were collected at 100(2)K on a SuperNova Agilent diffractometer and using CuKa radiation (λ = 1.54184 Å).
