摘要

＜正＞ Mr =.857. 08, monoclinic, space group Cc, unit cell parameters: α= 21. 966（3）, b=12. 479（2）,c=15. 924 （2）A ;β=116. 97（1）°;V = 3890. 2A3;Z=4; Dc= 1. 46gcm-3;F（000） = 1768. The final R factor is 0. 049 for 2774 reflections with Ⅰ≥3σ（Ⅰ）.The core Fe2NiO of molecule Fe2NiO（O2CCH3）6Py3 is planar and the ring planes of the three terminal pyridine ligands are all nearly perpendicular to it. The solvate pyridine is statically disordered in crystal.
