Reference of 14871-92-2, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 14871-92-2, Name is (2,2′-Bipyridine)dichloropalladium(II), molecular formula is C10H8Cl2N2Pd.

Concentration-dependent equilibria of molecular squares [Pd4(L?)4(L)4](NO3)8 and triangles [Pd3(L?)3(L)3](NO3)6 were obtained when cis-protected Pd(II) units [PdL?(NO3)2] (L? = tmeda, 2,2?-bpy, and phen) were combined independently with 4,4?-bipyridine (L) in water. However, complexation of [PdL?(OTs)2] with L resulted in exclusive formation of the corresponding molecular squares. The addition of AgOTs to each mixture of square and triangle led to a shift in the equilibrium, resulting in the disappearance of the triangles and exclusive formation of the corresponding squares. The crystal structures of the molecular squares [Pd4(L?)4(L)4](OTs)8 revealed a pair of tosylate anions encapsulated in the hydrophobic cavity of the square. Further, [Pd4(2,2?-bpy)4(L)4](OTs)8 and [Pd4(phen)4(L)4](OTs)8 exhibited solvatomorphism, yielding two crystalline forms each, respectively. The cationic units in these crystals associate through intermolecular pi···pi stacking interactions wherein the cis-protecting units (i.e., 2,2?-bpy and phen) of adjacent molecules overlap via side-on or end-on modes. Thus, the cations may be considered as “tectons”, each of which contains four peripheral 2,2?-bpy/phen units, which behave as “supramolecular synthons” in the self-assembly of the squares. The tosylates interact with the cations through C-H···O and C-H···pi interactions and play a role in the packing of the molecular squares.
