“…The syntheses of the ligand 1 and the ligand for the reference complex (5(Pd)) [7] were reported previously [6]. The desired palladium complex 3(Pd) was prepared by a treatment of Pd(AcO) 2 the polymeric structures, e.g., found in PtCl 2 , gave low yields of the products [6,8].…”

“…The desired palladium complex 3(Pd) was prepared by a treatment of Pd(AcO) 2 the polymeric structures, e.g., found in PtCl 2 , gave low yields of the products [6,8]. Therefore, a discrete complex, Pt(PhCN) 2 Cl 2 , was used for the preparation of 2(Pt) [6]. For the preparation of Pd complexes, treatments of such discrete metal sources, e.g., Pd(PhCN) 2 Cl 2 , were also reported [9].…”

“…1 (this notation, Complex #1 and Complex #2 for 3(Pd), corresponds to the notation used for 2(Pt) [6], a distorted Complex #1 and a planar Complex #2). [11], R = n Bu: 2.00(2) Å [12], respectively, and other structurally similar complexes, 1.989$1.993 Å [13,14].…”

“…Recently, we designed and synthesized p-expanded ligand based on pyrene (1) and demonstrated the synthesis of the corresponding platinum(II) complex, 2(Pt) [6]. The complex 2(Pt) takes the four-coordinate planar structure.…”
