Metal complex: determining the number of PPh3 ligands

  1. I keep getting x to be 1 in this problem

    ‘A complex is synthesised by combining Hydrated solutions of NiCl2 (0.6g) with 1.35g trimethylphosphine (PPh3). After cooling the product precipitates a s a solid with formula NiCl2(PPh3)x. Determine x.’

    I first found the atom ratio 0.6/129.593 and then 1.35/262.292 And the smallest ratio these go into gives x=1. I don’t think this was right?

    Any input to where I’ve gone wrong is greatly appreciated
