    • Synthesis of 1: Anhydrous VCl3 (0.126 g, 0.8 mmol) was taken with biphenylmethylphosphonic acid (0.08 g, 0.3 mmol) and NEt 3 (0.05 g, 0.5 mmol) in acetontrile in an Erlenmeyer flask and refluxed at 80°C for 30 min. The resultant clear green solution was filtered, and the filtrate was kept at room temperature. After 2 days, X-ray-quality green single crystals had grown. The initial and final pH values of the reaction were 2.5 and 3.0, respectively. The yield of the reaction was ∼20, on the basis of vanadium, Elem anal. Calcd, C, 43.54; H, 4.60; N, 2.46.

    • -1. 2 has also been synthesized following the same procedure as that for 1, except that the same equivalent of pyridine was taken instead of triethylamine. Large orange crystals were grown up from the solution, and an unidentified green oil separated out. The yield of the reaction was ∼20% (on the basis of vanadium).

Three atoms of the pyridine near sandwiched chlorides were symmetry-generated from the other three. So, the nitrogen atom could not be assigned. This is due to the fact that those pyridines are in different orientations in the packing and the X-ray data gave us an averaged diffraction pattern.
