摘要：

[(tBu)2P]2P-P[P(tBu)2]2 1 obtained at - 20-degrees-C from a solution of (tBu)2P-P = P(Br)tBu2 forms yellow crystals (regular hexagons). 1 crystallizes monoclinic in the space group C2/c with a = 2145.6 pm, b = 1137 pm, c = 1696.1 pm, beta = 110.75-degrees and Z = 4 formula units in the elementary cell. Due to high steric load the bond angles at the teritary P atoms with delta = 115.7-degrees are significantly larger than those at the primary P atoms with delta = 108.6-degrees.
