摘要

A fluorinated mixed-metal phosphate containing indium and cobalt in 1:1 ratio, [enH2][CoIn(PO4)2H(OH2) 2F2], 1, has been synthesized by hydrothermal methods from a gel-composition of 1.0 Co(OAc)2: 1.0 In(OAc)3: 2.0 H3PO4: 2.0 en: 2.0 HF: 240 H2O. Large pale pink-purple single crystals (200 μm) were formed in 70% yield based on cobalt, with only minor amorphous impurity phases. Compound 1 is triclinic, space groupP1,a=5.217(1),b=7.596(2),c=8.904(2) Å,α=109.11(1),β=97.46(1),γ=109.95(1)°,V=301.6(1) Å3. The magnetic moment is 5.02 BM, indicating a d7high-spin Co2+center. Fluoride is crucial to formation of the mixed-metal phase since the In and Co metals are connected to each other by bent F-bridges, as well as hydrogen phosphate groups, which connect the (Co-F-In) chains into a 2-D sheet structure.
