Abstract:	The synthesis of the first terphenyl-based sodium phosphanide, namely DmpP(H)Na (1) (Dmp=2,6-dimesitylphenyl) as well as the X-ray crystal structure determination of a crown ether adduct of the sodium salt, namely DmpP(H)Na(15-crown-5) (2) are reported. Compound 2 crystallizes in the triclinic space group P1?. Crystal data for 2 at 198 K: a=10.5342(4) Å; b=12.0538(5) Å; c=14.4023(6) Å; α=79.9474(9)°; β=72.2234(10)°; γ=70.0716(10)°; V=1632.1(2) Å³; Z=2; D_calc=1.198 g cm⁻³; R_F=7.91%. The molecular structure of 2 features a monomeric arrangement in the solid state and a bent NaPC(ipso) moiety [Na(1)P(1)C(16)=116.3(2)°].
