Three di-Schiff-base ligands, N,N 0-bis(salicylidene)-1,3-propanediamine (H2Salpn), N,N 0-bis(salicylidene)-1,3-pentanediamine (H2Salpen) and N,N 0-bis(salicylidine)-ethylenediamine (H2Salen) react with Ni(SCN)2 Æ 4H2O in 2:3 molar ratios to form the complexes; mononuclear [Ni(HSalpn)(NCS)(H2O)] Æ H2O (1a), trinuclear [{Ni(Salpen)}2Ni(NCS)2] (2b) and trinuclear [{Ni(Salen)}2Ni(NCS)2] (3) respec...

The tetra-nuclear title complex, [Ni4(C14H11NO2)4(CH3OH)4]·0.8CH3OH, has a distorted cubane topology shaped by four Schiff base ligands. The cubane [Ni4(μ3-O4)] core is formed via the O atoms from the Schiff base ligands. The octa-hedrally coordinated NiII ions occupy alternating vertices of the cube. Each NiII ion is coordinated by one O,N,O'-tridentate dianionic ligand, two O atoms of oxidoph...

Department of Chemistry, Kongunadu Arts and Science College, Coimbatore – 641029, India Post Graduate and Research Department of Chemistry, Sri Ramakrishna Mission Vidyalaya College of Arts and Science, Coimbatore – 641020, India. ABSTRACT: Six new organosoluble ruthenium(II) complexes bearing dibasic tetradentate Schiff base ligands of the general formula [Ru(CO)(PPh3)(L)] (where L = dibasic t...

In the title complex, [Ni(2)(C(14)H(17)NO(4))(2)(C(12)H(8)N(2))(2)]·4CH(3)OH·3H(2)O, the two Ni(II) ions are bridged by two Schiff base anions, leading to a dinuclear complex. One Ni(II) ion is six-coordinated by four O atoms and two N atoms of two tridentate Schiff base ligands derived from the condensation of l-isoleucine and o-vanillin. The other Ni(II) ion is six-coordinated by four N atoms...

In the title complex, [Zn(C(11)H(12)NOSe(2))(2)], the Zn(II) atom is four-coordinated by two O,N-bidentate Schiff base ligands in a distorted tetra-hedral geometry.

In the title mononuclear nickel(II) complex, [Ni(C(13)H(15)ClNO)(2)], the Ni(II) atom is four-coordinated in a tetra-hedral geometry by the N and O atoms of the two Schiff base ligands.
