A novel and simple synthetic way using NaBH₄ in the mixure of H₂O-THF was applied to prepare 1,2-bis(diphenylphosphinoborane)ethane, dppe(BH₃)₂, in high yield and purity. The phosphanylborohydride compound dppe(BH₃)₂ was isolated in the form of colorless crystals and characterized by single crystal X-ray diffraction, ¹H, ¹³C, ³¹P and ¹¹B NMR spectroscopy. Prismatic colorless crystals of dppe(BH3)2 were obtained in monoclinic crystal system and space group P21 with two asymmetric units in the unit cell. Lattice parameters were: a = 11.657(2), b = 17.237(2), c = 12.764(2) Å, β = 98.735(14)°, 2535.0(7) ų
