AbstractThe sodium pentaphosphide dimer [(tBu3Si)3P5Na2(THF)]2 has been synthesized in high yield from the reaction of four equivalents of the sodium silanide tBu3SiNa with P4. X‐ray quality crystals of the sodium pentaphosphide dimer [(tBu3Si)3P5Na2(THF)]2 (monoclinic, P21/n) were grown from benzene. The sodium pentaphosphide (tBu3Si)3P5Na2 can be oxidized with one equivalent of TCNE to give the bicyclo[2.1.0]pentaphosphane (tBu3Si)3P5; it also reacts with AgOCN to give the silver pentaphosphide [(tBu3Si)3P5Ag2]2 (monoclinic, P21/n). Crystals of the pentaphosphane (tBu3Si)3P5 (monoclinic, P21/c) suitable for X‐ray diffraction were obtained from hexane at –25 °C. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
