A new water soluble heterometallic polymeric complex [{(PTA)2
CpRu-l-CN-1jC:2j2N-RuCp(PTA)2}-l-{Au(CN)4}4]n 2H2O (1) is synthesized
and characterized by single crystal X-ray diffraction. This
complex self-assembles forming 3D polymeric structures with large
scale hexagonal conformation. They also organize as 3D stacks of
polymer sandwiches that can be exfoliated providing mono
heterometallic-3D layers, as shown by electron microscopy.
Regarding the polymer dynamics, quasi-elastic neutron scattering
shows a transition from vibrational Debye–Waller behaviour to a
more dynamically active state as a result of the loss of structural
water molecules.
