Following the recent discovery of a new family of hybrid ABX perovskites where X=(H POO) (hypophosphite), this work reports a facile synthesis for mixed X-site formate perovskites of composition [GUA]Mn(HCOO) (H POO) , with two crystallographically distinct, partially ordered intermediate phases with x=0.84 and 1.53, corresponding to ca. 30 and 50 mol % hypophosphite, respectively. These phases are characterised by single-crystal XRD and solid-state NMR spectroscopy, and their magnetic properties are reported.
最近发现了一类新型的 ABX 杂化钙钛矿，其中 X=(HPOO)（次膦酸盐），本工作报道了一种简便的合成方法，用于制备组成[GUA]Mn(HCOO)(HPOO)的混合 X 位甲酸盐钙钛矿，其中存在两个结晶学上不同的、部分有序的中间相，x 值分别为 0.84 和 1.53，对应于约 30 和 50 mol%的次膦酸盐。这些相通过单晶 XRD 和固态 NMR 光谱进行了表征，并报道了它们的磁性性质。
