The solid-state behaviour of two series of isomeric, phenol-substituted, aminomethylphosphines, as the free ligands and bound to Pt II , have been extensively studied using single crystal X-ray crystallography. In the first library, isomeric diphosphines of the type Ph 2 PCH 2 N(Ar)CH 2 PPh 2  [ 1a – e ; Ar = C 6 H 3 (Me)(OH)] and, in the second library, amide-functionalised, isomeric ligands Ph 2 PCH 2 N{CH 2 C(O)NH(Ar)}CH 2 PPh 2  [ 2a – e ; Ar = C 6 H 3 (Me)(OH)], were synthesised by reaction of Ph 2 PCH 2 OH and the appropriate amine in CH 3 OH, and isolated as colourless solids or oils in good yield. The non-methyl, substituted diphosphines Ph 2 PCH 2 N{CH 2 C(O)NH(Ar)}CH 2 PPh 2  [ 2f , Ar = 3-C 6 H 4 (OH);  2g , Ar = 4-C 6 H 4 (OH)] and Ph 2 PCH 2 N(Ar)CH 2 PPh 2  [ 3 , Ar = 3-C 6 H 4 (OH)] were also prepared for comparative purposes. Reactions of  1a – e ,  2a – g , or  3  with PtCl 2 (η 4 -cod) afforded the corresponding square-planar complexes  4a – e ,  5a – g , and  6  in good to high isolated yields. All new compounds were characterised using a range of spectroscopic ( 1 H,  31 P{ 1 H}, FT–IR) and analytical techniques. Single crystal X-ray structures have been determined for  1a ,  1b ∙CH 3 OH,  2f ∙CH 3 OH,  2g ,  3 ,  4b ∙(CH 3 ) 2 SO,  4c ∙CHCl 3 ,  4d ∙½Et 2 O,  4e ∙½CHCl 3 ∙½CH 3 OH,  5a ∙½Et 2 O,  5b ,  5c ∙¼H 2 O,  5d ∙Et 2 O, and  6 ∙(CH 3 ) 2 SO. The free phenolic group in  1b ∙CH 3 OH,  2f ∙CH 3 OH ,   2g ,  4b ∙(CH 3 ) 2 SO,  5a ∙½Et 2 O,  5c ∙¼H 2 O, and  6 ∙(CH 3 ) 2 SO exhibits various intra- or intermolecular O–H∙∙∙X (X = O, N, P, Cl) hydrogen contacts leading to different packing arrangements.
