The title compound, [PtCl2(C13H26NP)(2)], is a rare example of a sterically bulky ligand adopting a cis geometry in a square-planar complex. It crystallizes on a twofold rotation axis which bisects the Pt centre and the P-Pt-P' and Cl-Pt-Cl' angles. The ligand exhibits a random packing disorder in the N,N-dimethylpropylamine substituent, with the two orientations refining to occupancies of 0.404(15) and 0.596 (15). Weak intermolecular interactions between a Cl and a H atom of the ligand of a neighbouring molecule result in extended chains along the a axis. The effective cone angle for the dimethyl[3-(9-phosphabicyclo[3.3.1]non-9-yl)propyl]amine (Phoban[3.3.1]-C3NMe2)ligand was determined as being in the range 160-181 degrees, depending on the choice of atoms used in the calculations.
