Self-assembly of a functional cryptand core（1） having six dithiocarbamate groups and \{（dppm）Au2Cl\}2 in methanol followed by the addition of excess NH4PF6 affords a novel metallodendritic supramolecule（2）. This dendritic supramolecule was characterized by NMR, MS, XPS, IR, UV-Vis, luminescence spectra and elemental analyses. The results show the concentration-dependent absorption and luminescent properties in acetonitrile solution for the title compound, which may be closely related to the intramolecular and intermolecular aggregation of digold（Ⅰ） branches through Au（Ⅰ）…Au（Ⅰ） interactions.
A dipyrazol-bridged macrocyclic palladium(II) complex [{Pd(en)}4L4](NO3)8 (en=ethylenediamine, L=3,3′,5,5′-tetramethyldipyrazol) 1 was prepared in water through a macrocyclization of cis-(ethylenediamine)Pd(II) nitrate and the neutral form of the dipyrazol ligand 3,3′,5,5′-tetramethyldipyrazol. This cationic palladium macrocycle is highly distorted rather than a planar macrocycle and can hold eight nitrate anions around the macrocyclic framework through both hydrogen bonding and electrostatic interactions. CCDC: 192017.
