   We report on spectroscopic measurements on the 4 f 7 6 s 2 8 S 7 / 2 ∘ → 4 f 7 ( 8 S ∘ ) 6 s 6 p ( 1 P ∘ ) 8 P 9 / 2 transition in neutral europium-151 and europium-153 at 459.4 nm. The center of gravity frequencies for the 151 and 153 isotopes, reported for the first time in this paper, to our knowledge, were found to be 652,389,757.16(34) MHz and 652,386,593.2(5) MHz, respectively. The hyperfine coefficients for the 6 s 6 p ( 1 P ∘ ) 8 P 9 / 2 state were found to be A ( 151 ) = − 228.84 ( 2 ) M H z , B ( 151 ) = 226.9 ( 5 ) M H z and A ( 153 ) = − 101.87 ( 6 ) M H z , B ( 153 ) = 575.4 ( 1.5 ) M H z , which all agree with previously published results except for A(153), which shows a small discrepancy. The isotope shift is found to be 3163.8(6) MHz, which also has a discrepancy with previously published results.

   Kagome strip phases are potential quantum materials due to their complex magnetic interactions that can be traced to their hybrid one-dimensional (1D) and two-dimensional (2D) structural motifs. Using a high-temperature hydrothermal method, the designed synthesis and crystal growth of a broad general class of Kagome strip materials with the formula A2M3(XO4)2(OH)2, where M is a range of divalent transition metal ions with differing spin values, are reported herein. An attempt to replace hydroxide with fluoride led to Na2M3(PO4)2F2 in a new structure type with 1D chains of half-delta transition metal arrangements. In both cases, the crystals were grown large enough to align in an external magnetic field, enabling future studies of their anisotropic magnetic properties. The structures are compared to one another with analysis of the importance of hydrogen bonding in the structure formation to enable future design of magnetically frustrated crystals.Not Available
