The reaction of CH₃COC₅H₄(CO)₃MoSnCl₃ with 2,4-dinitrophenyl-hydrazine yielded the corresponding hydrazone, Cl₃SnMo(CO)₃C₅H₄(CH₃)C=N-NHC₆H₃(NO₂)₂ (1). Crystals of 1 are monoclinic; a = 8.6724(9), b = 21.549(2), c = 12.378(1) A, β= 102.099(8)°, space group, P2₁/n, Z = 4, Mo-Sn distance 2.7040(7) A. The reaction of CH₃COC₅H₄(CO)₃WSnCl₃ with benzoyl-hydrazine in refluxing ethanol gave μ[C₅H₄(CH₃)C=N-N=C(O)PH]W-SnCl₂(C₂H₅OH)₂ (2). Crystals of 2 are monoclinic, a = 16.897(2), b = 13.780(1), c = 12.429(2) A, β = 116.80(1)°, space group Cc, Z = 4, W-Sn distance 2.7767(9) A.
