N-(m-ferrocenylphenyl)-formamide has been synthesized by the reaction of m-ferrocenyl-aniline with DMF, and characterized by elements analysis, IR, 1H NMR, and X-ray structure determination. The crystallized was in the monoclinic, P21/c space group, with a=0.140 94(3) nm, b=0.102 87(2) nm, c=0.100 26(2) nm, β=104.85(3)° and final R indices [I>2σ(I)] R1=0.072 7, wR2=0.184 5. An infinite one-dimensional chain is formed by intermolecular hydrogen bonding N-H...O. Cyclic voltammetry was studied comparing with the parent compound (m-ferrocenylaniline). CCDC: 243511.
S A new cyclomercurated ferrocenylketimine containing pyridyl ring ([HgCl(5- C5H3C(CH3)=N-3-C5H4N)Fe(5-C5H5)]紺H2Cl2, 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) ? b = 100.32(3)o, V = 1823.7(6) 3, Z = 4, C17.5H16Cl2FeHgN2, Dc = 2.119 g/cm3, m = 9.497 mm-1, F(000) = 1100, R = 0.0436 and wR = 0.0987. The independent reflections are 3527, of which 3153 with I ≥ 2s(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) ? respectively.
