“…On the one hand, a survey of the CSD revealed that, in the few known penta-coordinated [Zn(R-bpa)Br 2 ] complexes, the bpa ligand is bound to the central metal as mer -isomer. ,,,, On the other hand, even for a significantly broader class of compounds, namely, [M(R-bpa)X 2 ] complexes containing any transition metal M or any halogen ions X, the bpa fac -isomer was found relatively rarely in the solid state, with only a handful of structures in the literature. ,− …”

A variety of structurally different complexes of the isopropyl-bis(2-picolyl)amine ( i Pr-bpa) ligand were prepared with ZnA2 and CuA2 salts (A = Br–, Br–/PF6 –, BF4 –/F–, ClO4 –). The choice of different counterion affected the stoichiometry, coordination number, geometry, and formation of geometrical isomers. Crystal structures of four Zn(II) complexes, namely, two monomers ( mer -[Zn( i Pr-bpa)Br 2 ] and fac -[Zn( i Pr-bpa)Br 2 ]), one F–-bridged dimer ([Zn 2 (μ-F) 2 ( i Pr-bpa) 2 ](BF 4 ) 2 ), and one ML 2 complex ([Zn( i Pr-bpa) 2 ](ClO 4 ) 2 ) were determined, and their solution structures were studied by NMR spectroscopy. For the ML 2 complex, relative stabilities of geometrical isomers were determined using density functional theory calculations. For Cu(II) complexes, five crystal structures were determined, namely, two monomers ([Cu( i Pr-bpa)Br 2 ] and [Cu( i Pr-bpa)(ClO 4 ) 2 (H 2 O)]), a Br–-bridged dimer ([Cu 2 (μ-Br)(Br) 2 ( i Pr-bpa) 2 ](PF 6 )), a F–-bridged coordination polymer ([Cu(μ-F)( i Pr-bpa)] n (BF 4 ) n × nCH 3 OH), and a cyclic, CO3 2–-bridged trimer ([Cu 3 (tri-μ-CO 3 )(ClO 4 ) 3 ( i Pr-bpa) 3 ](ClO 4 )). The different crystallographic structures of Cu(II) complexes are reflected in their different magnetic properties investigated by electron spin resonance spectroscopy and magnetic susceptibility measurements.

“…The N2-Cu1-N3, N3-Cu1-N1 and N1 pyridine -Cu1-N2 pyridine bite angles of 77.91(6)°, 82.31(6)°and 105.18(6)°respectively,correlates well with similar complexes of dipyridylamine ligands with Cu(II). All the bond distances and angles in the title structure fall within the range of similar complexes [14][15][16][17][18], with the exception of aclosely related blue Cu(II) complex containing ad ichloromethane solvate which crystallized in the C2/c space group [19].

A series of late transition metal complexes, [(bpma)Co(μ–Cl)Cl]2, [(bpma)Cu(μ–Cl)Cl]2, [(bpma)Zn(μ–Cl)Cl]2 and [(bpma)Cd(μ–Br)Br]2 (where bpma is 4‐bromo‐N‐((pyridin‐2‐yl)methylene)benzenamine) have been synthesized and structurally characterized. The X‐ray structures of dimeric complexes [(bpma)M(μ–X)X]2 (M = Co, Cu and Zn, X = Cl; M = Cd, X = Br) showed a distorted 5‐coordinate trigonal bipyramidal geometry involving two nitrogen atoms of N,N‐bidentate ligand, two bridged and one terminal halogen atoms. The complex [(bpma)Cu(μ–Cl)Cl]2 revealed the highest catalytic activity for the polymerisation of methyl methacrylate in the presence of modified methylaluminoxane with an activity of 9.14 × 104 g PMMA/mol·Cu·h at 60 °C and afforded syndiotactic poly (methylmethacrylate) (rr = 0.69).
