摘要：

WCl4Py2 (Py = Pyridine) crystallizes in the monoclinic space group: I2/m, with a = 7.237(1), b = 7.278(2), c = 12.865(4) Å, β = 94.60(2)°, and Z = 2. WCl4Py2 has 2/m crystallographic symmetry requiring trans position of the ligands. WCl and WN bond lengths are 2.347(1) and 2.181(4) Å. WCl4Py2 is isostructural with WBr4Py2. WX4Pic2 (Pic = 4‐methylpyridine) can be obtained from WX4Py2 and 4‐methylpyridine at room temperature. Chemical and physical evidence speaks for the trans structure of WX4Pic2.
