Structure of bis(1,3-diphenyl-1,3-propanedionato-O,O')(1,2-ethanediamine-N,N')nickel(II)

Bis[6-(cyclopentyliminomethyl)-2-methoxyphenolato]nickel(II)

“…The Schiff base acts as a bidentate ligand through the phenolate O and the imine N atoms. The bond lengths and angles (Table 1) for the Ni atom are typical, and comparable to those in other Schiff base-nickel(II) complexes (Gomes et al, 1999;Jircitano et al, 1990;Kabak et al, 1997).…”

Bis{2-[2-(diethylammonio)ethyliminomethyl]-4-nitrophenolato}dimethanolnickel(II) dinitrate

“…The coordination sites are occupied by four donor atoms from two Schiff base ligands and two O atoms from two methanol molecules, giving a slightly distorted octahedral geometry. All the bond lengths (Table 1) around the metal centre are comparable with those of similar compounds (Gomes et al, 2000;Arıcı et al, 2005;Jircitano et al, 1990).…”

{2-Bromo-4-chloro-6-[2-(dimethylamino)ethyliminomethyl]phenolato}thiocyanatonickel(II)

“…The two trans angles subtended at the Ni II atom deviate slightly from 180 (Table 1), and the other angles around the Ni II atom deviate slightly from the ideal value (90 ) for a square-planar coordination, ranging from 83.9 (2) to 92.5 (2) . The Ni-O and Ni-N bond lengths are typical and comparable to those in similar Schiff base-nickel(II) complexes (Gomes et al, 1999;Jircitano et al, 1990;Kabak et al, 1997).…”
