Coordination Chemistry of P-Rich Phosphanes and Silylphosphanes. XXVI [1] Formation and Structure of [{cyclo-P4(P(t)Bu2)4}{Ni(CO)2}2]

[{cyclo-P4(P(t)Bu2)4}{Ni(CO)2}2] is formed by reaction of the cyclotetraphosphane P4(P(t)Bu2)4 with [Ni(CO)4]. Each Ni(CO)2 unit is coordinated by two adjacent (t)Bu2P groups forming two five-membered P4Ni rings above and below the planar cyclotetraphosphane ring, respectively. The compound crystallizes in the triclinic space group P1- (No. 2) with a=893.29(5), b=1140.75(7), c=1235.52(8) pm, α=109.179(7), β=100.066(7), γ=97.595(7)° and Z=1.
