Bis(2-ethoxy-6-formylphenolato-κ2 O 1,O 6)nickel(II)
The title compound, [Ni(C(9)H(9)O(3))(2)], was synthesized by the reaction of 3-ethoxy-salicylaldehyde with nickel(II) nitrate in methanol solution. The asymmetric unit onsists of two half-molecules; each Ni atom lies on a centre of symmetry. The Ni(II) ions are coordinated by four O atoms from two deprotonated 3-ethoxy-salicylaldehyde ligands in a slightly distorted square-planar coordination ...

The title complex, [Nd(2)(C(8)H(3)NO(6))(2)(C(8)H(4)NO(6))(2)(H(2)O)(6)]·2H(2)O, consists of dimeric units related by an inversion center. The Nd(III) atom is nine-coordinated by three O atoms from water mol-ecules and six from carboxyl-ate atoms. The 1,2-dicarboxylate acid molecules are in a single and double deprotonation stage and exhibit two coord-in-ation modes, viz. μ(2)-(κ(4), O(1): O(2)...
متن کاملBis{2-bromo-4-chloro-6-[2-(phenylsulfonyl)hydrazonomethyl]phenolato-κ2 N,O 1}copper(II)
The Cu atom in the title compound, [Cu(C(13)H(9)BrClN(2)O(3)S)(2)], is chelated by two deprotonated Schiff base ligands in a square-planar coordination geometry; the Cu atom lies on a center of inversion. The -NH- group of one anion forms an intra-molecular hydrogen bond to the phenolate atom of the symmetry-related ion.
متن کاملBis[2-(benzylamino)pyridine-κN](2-formyl-6-methoxyphenolato-κ2 O 1,O 6)(nitrato-κ2 O,O′)nickel(II)
In the title compound, [Ni(C(8)H(7)O(3))(NO(3))(C(12)H(12)N(2))(2)], the asymmetric unit contains a Ni(II) atom, two mol-ecules of 2-(benzyl-amino)pyridine, a mol-ecule of deprotonated o-vanillin (3-methoxy-salicylaldehydate) and a bidentate nitrate anion. The Ni(II) center is six-coordinated by two pyridine N atoms from 2-(benzyl-amino)pyridine, two O atoms from o-vanillin and two O atoms from...
متن کاملBis{2-methoxy-6-[(4-methylphenyl)iminiomethyl]phenolato-κ2 O 1,O 2}tris(nitrato-κ2 O,O′)methanolsamarium(III)
The asymmetric unit of the title compound, [Sm(NO(3))(3)(C(15)H(15)NO(2))(2)(CH(3)OH)], contains two Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolate (HL) ligands, three nitrate ions and one methanol mol-ecule that binds to the nine-coordinate samarium(III) ion via its O atoms. The HL ligands chelate with a strong Sm-O(deprotonated phenolic) bond and a weak Sm-O(meth-oxy) con...
