摘要：

Cp2ZrCl2 reacts with Li(THF)2PHCy (Cy = C6H11) to yield the metallacyclic compound Cp2Zr(PCy-PCy-PCy) 1. The P-31{H-1} NMR spectrum of 1 shows a coupling pattern for an A2X system, indicating the presence of only the meso-forms in solution, which are also present in the solid state. 1 crystallizes in the monoclinic space group P2(1)/n (No. 14) with a = 12.984(8), b = 9.241(7), c = 23.05(1) angstrom, beta = 93.48(4)-degrees, V = 2760.1 angstrom3 and four formula units in the unit cell (2718 independent observed reflections, R = 7.3%). The central ZrP3 ring in 1 is almost planar. The Zr-P bond lengths of 2.618(4) and 2.628(4) angstrom are nearly identical.
