    Description / Table of Contents: Coordination Chemistry of P-rich Phosphanes and Silylphosphanes. XIII [1]. [η2-{tBu2P—P=PtBu2} PtBr(PPh3)][η2-{tBu2P—P=PtBu2} PtBr(PPh3)] 1 is the first transition metal complex compound resulting from a phosphino-phosphinidene-phosphorane. The yellow crystals of 1 (fp. 201-203°C, decomp.) were obtained by reacting tBu2P—P=P(Br)tBu2 with either (Ph3P)2Pt · C2H4, or with Pt(PPh3)4, resp. Compound 1 crystallizes triclinic in the space group P1 (no. 2) with a = 1076.80(8) pm, b = 1344.61(8) pm, c = 1381.16(9) pm, α = 81.773(6)°, β; = 85,110(8), γ = 88,776(7).
    Notes: [η2-{tBu2P—P=PtBu2} PtBr(PPh3)] 1 ist die erste Komplexverbindung aus einem Phosphino-phosphiniden-phosphoran. Die gelben Kristalle von 1, Smp. 201-203°C (unter Zersetzung) bilden sich bei der Umsetzung von tBu2P—P=P(Br)tBu2 mit (Ph3P)2Pt · C2H4 oder Pt(PPh3)4. 1 kristallisiert triklin in P1 (Nr. 2) mit a = 1076,80(8) pm, b = 1344,61(8) pm, c = 1381,16(9) pm, α = 81,773(6)°, β; = 85,110(8)°, γ = 88,776(7).
