tBu2P-P=P(R)tBu2 (R = Br, Me) reacts with [Ni(CO)4] yielding [{cyclo-P3(PtBu2)3}{Ni(CO) 2}{Ni(CO)3}]. The two cis-tBu2P substituents of the cyclotriphosphane, which results from the trimerization of the phosphinophosphinidene tBu2P-P, are coordinating to a Ni(CO)2 unit forming a five-membered P4Ni chelate ring. The trans-tBu2P group is linked to a Ni(CO)3 unit. The compound crystallizes in the orthorhombic space group Pbca (No. 61) with a = 933.30(5), b = 2353.2(1) and c = 3474.7(3) pm.

[{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.
