Fe(II) complex,thiourea,crystal structure,synthesis,4,5-diazafluoren-9-one
The title compound Fe(CH4N2S)2Cl2·(2(C11H6N2O) (Mr = 643.35) has been prepared and its crystal structure was determined by X-ray diffraction method with the following data: triclinic, space group P1,a = 7.3742(10), b = 13.0427(12), c = 15.215(2)A, α= 88.969(12), β= 78.004(12), γ= 79.689(11)o, V = 1408.1(3)A3, Z = 2, Dx = 1.517 g/cm3, μ= 0.912 mm-1 and F(000) = 656. The final R = 0.030 and wR = 0.078 for 4070 observed reflections (I > 2σ(I)), and R = 0.064 and wR = 0.091 for 5516 independent ones. The crystal consists of tetrahedral Fe(II) complex and hydrogen bonded 4,5-diazafluoren-9-one (dafone). The carbonyl bridge in dafone distorts the bipyridine moiety and results in the longer N…N separation of 3.071(3) and 3.061(3)A. There exists an extensive intermolecular hydrogen bond network in the crystal, andπ-π stacking is observed between the neighboring dafone rings.
