Key Points

Determine the crystal structure and crystallographic parameters of the erbium(III) coordination complex pyridinium tetrakis(1,1,1-trifluoro-2,4-pentanedionato-κ²O,O′)erbium(III).
Performs single-crystal X-ray diffraction at T = 293(2) K on crystalline C25H22F12ErNO8.
Solves and refines the crystal structure, calculating residual indices Rgt(F) and wRref(F²).
The compound crystallizes in the monoclinic space group P2₁/c with unit cell dimensions a = 10.57530(10) Å, b = 19.7166(2) Å, c = 15.7729(1) Å, β = 103.3710(10)°, and V = 3199.64(5) Å³ with Z = 4.
The final crystallographic refinement converges to residual agreement factors of Rgt(F) = 0.0365 and wRref(F²) = 0.1050.

Implication
