Formation of structurally different solvated and non-solvated [Ni(PTSC)(PPh3)] (PTSC = salicylaldehyde-N-phenylthiosemicarbazide anion) crystals from single pot

New thiosemicarbazone nickel(II) complex, derived from salicylaldehyde-N -phenylthiosemicarbazone, was synthesized and characterized by means of IR, electronic, and mass spectral techniques. Its two different types of crystal structures were also characterized by single crystal X-ray diffraction technique and reported here. In type A, the complex crystallizes in the monoclinic space group P 21/c with four molecules per cell and has the dimensions of a = 9.2066(7), b = 19.1090(13), c = 18.589(2) Å, β = 92.87 (1)°. In type B, the complex crystallizes in the triclinic space group View the MathML sourceP1¯ with two molecules per cell and has the dimensions of a = 10.406(4), b = 10.876(4), c = 14.614(5) Å, α = 64.81(1), β = 74.07(2), γ = 70.85(2)°
