cyclomercurated ferrocenylimine%pyridyl compounds%crystal structure
A new cyclomercurated ferrocenylketimine containing pyridyl ring ([HgCl(η5- C5H3C(CH3)=N-3-C5H4N)Fe(η5-C5H5)]·1/2CH2Cl2, Mr = 581.66) was synthesized and its molecular structure has been confirmed by IR, elemental analysis, 1H-NMR and X-ray crystal structure analysis. It is of monoclinic system, space group P21/c with a = 9.213(2), b = 17.479(4), c = 11.510(2)A, β= 100.32(3)°, V = 1823.7(6) A3, Z = 4, C17.5H16Cl2FeHgN2, Dc = 2.119 g/cm3,μ = 9.497 mm－1, F(000) = 1100,Wr = 0.0436 and Wr = 0.0987. The independent reflections are 3527, of which 3153 with I ≥ 2σ(I) were observed. The compound contains a five-membered metallocycle. The mercury atom is bonded with the 2-position of substituted cyclopentadienyl ring (Cp), and coordinated weakly to the N atom of imino group. The pyridyl ring is almost perpendicular to the substituted Cp which is nearly coplanar with the metallocycle. The Hg(1)-C(1) and Hg(1)-Cl(1) bond lengths are 2.050(8) and 2.321(2)A,respectively.
