The complexes Co(NO)(CO)(Ph₂PH)₂ (1), Fe(NO)₂(Ph₂PH)₂ (2) and Mn(NO)(CO)₂(Ph₂PH)₂ (3) are synthesized from Co(NO)(CO)₃, Fe(NO)₂(CO)₂ and Mn(NO)(CO)₄ respectively. Deprotonation of 1 with two equivalents of BuLi followed by subsequent addition of methyl iodide, allyl bromide and propargyl bromide provides Co(NO)(CO)(Ph₂PMe)₂ (4), Co(NO)(CO)(Ph₂PCH₂CHCH₂)₂ (5) and Co(NO)(CO)(Ph₂PCH₂CCH)₂ (6) respectively. X-ray crystal structure analyses for 1, 3 and 4-6 were carried out to give data as followed. 1: monoclinic; C2/c; Z = 4; a = 17.130(5), b = 9.894(2) and c = 42.607(1) A; β = 93.29(2)°; V = 7210(2) A3; R = 0.056; R_w = 0.058. 3: monoclinic; C2/c; Z = 4; a = 15.231(5), b = 10.247(2) and c = 16.311(2) A; β = 102.29(2)°; V= 2488(1) A3; R = 0.041; R_w = 0.042. 4: monoclinic; C2/c; Z = 4; a = 15.556(3), b = 12.072(1) and c = 14.809(2) A; β 114.43(1)°; V= 2532.0(7) A3; R = 0.032; R_w = 0.031. 5: monoclinic; P2₁/c; Z = 4; a = 15.427(2), b = 10.118(2) and c = 18.793(6) A; β = 102.56(1)°; V = 2863(1) A3; R = 0.042; R_w = 0.046. 6: monoclinic; P2₁/n; Z = 4; a = 9.3393(8), b = 19.035(4) and c = 16.007(1) A; β = 94.912(7)°; V= 2845.8(6) A3; R = 0.052; R_w = 0.059.
