Abstract

A composition space diagram is used to establish the stability regions of hybrid fluoroaluminates synthesized by solvothermal reactions in the Al(OH) ₃-HguaCl-HF_aq-EtOH system. The syntheses are conducted using microwave heating at 190 °C for 1 h. The structures of two new guanidinium fluoroaluminates, (H₃O)₂-[HgUa] ₁₆(Al₄F₁₈)₃.H₂O and [Hgua]₂-(Al₅F₁₇), are reported. (H ₃O)₂-[Hgua]₁₆-(Al₄F ₁₈)₃-H₂O, determined from single-crystal X-ray data, consists of discrete (Al₄F₁₈)^6- polyanions, while [Hgua]₂-(Al₅F₁₇), solved from powder X-ray diffraction data in direct space, contains unprecedented Al ₅F₁₇ layers constructed from the intergrowth of HTB and perovskite columns. A disorder of H₂O and H₃O+ is evidenced in (H₃O)₂-[Hgua]₁₆-(Al ₄F₁₈)₃-H₂O together with a disorder of guanidinium cations in the interlayer space of [Hgua]₂-(Al ₅F₁₇). (
