Two stoichiometric metal-organic frameworks containing Eu$^{3+}$ cations are probed as candidates for photon-based quantum information storage. Synthesis procedures for growing 0.2 mm, rod-shaped Eu(HCOO)$_3$ and 1-3 mm, rhombohedral Eu(HCOO)$_{3}\cdot$(HCONH$_2$)$_2$ single crystals are presented with visible precipitation as soon as 1 h into heating for Eu(HCOO)$_3$ and 24 h for Eu(HCOO)$_{3}\cdot$(HCONH$_2$)$_2$. Room temperature and 1.4 K photoluminescence measurements of the $^5$D$_{0}\rightarrow {^7}$F$_J$ transitions of Eu$^{3+}$ are analyzed for both compounds. Comparisons of peak width and intensity are discussed along with the notable first report for both of the $^5$D$_{0}\rightarrow {^7}$F$_0$ transition, the hyperfine structure of which has potential use in quantum memory applications. The air instability of Eu(HCOO)$_{3}\cdot$(HCONH$_2$)$_2$ and the transformation of its photoluminescence properties are discussed.
