Anomalous small‐angle X‐ray scattering was employed to monitor in situ the formation of colloidal Pt particles by the reaction of Pt(acac) 2 and Al(CH3) 3 in solution. An intermediate complex molecule was found to decompose to form stable Pt particles of 1.2 nm diameter with a monomodal particle size distribution. A network like correlation in the particle positions tends to build up by organic spacer molecules between stabilizing aluminum–organic shells.
