چکیده
In the crystal structure of the zinc(II) complex of bicine, [Zn(C(6)H(12)NO(4))(2)], the deprotonated amino acid O,N,O'-chelates to the metal atom through a carboxyl-ate O atom, a hy-droxy O atom and the N atom, the three atoms occupying fac positions of the distorted octa-hedron surrounding the metal atom. The metal atom lies on a center of inversion. The uncoordinated carboxyl-ate O atom is hydrogen bonded to the hy-droxy groups of adjacent mol-ecules, these two hydrogen bonds leading to the formation of a three-dimensional network.

In the title salt, [Zn(C6H15NO3)2](C8H4O4), the Zn(II) cation, located on a centre of inversion, is coordinated by four O atoms and two N atoms from two tridentate 2-[bis-(2-hy-droxy-eth-yl)amino]-ethanol (BHEA) ligands, giving rise to a slightly distorted octa-hedral geometry. The terephthalate dianion, located about a centre of inversion, is not coordinated to Zn(II) but is connected through ...

The reaction of zinc acetate and 2-methyl-8-hydroxy-quinoline in methanol yielded the centrosymmetric dinuclear title compound, [Zn(2)(C(10)H(8)NO)(2)(CH(3)CO(2))(2)(CH(3)OH)(2)], which has the Zn atom within a distorted NO(4) trigonal-bipyramidal coordination geometry. Methanol-acetate O-H⋯O hydrogen bonds link the dinculear units into a linear supra-molecular chain extending parallel to [100].

In the centrosymmetric dinuclear title compound, [Pb(2)(C(10)H(6)NO(2))(2)(CH(3)COO)(2)(C(2)H(5)OH)(2)], one O atom of the carboxyl-ate group of the quinoline-2-carboxyl-ate anion connects the two Pb(II) atoms. The Pb(II) atom is surrounded by four O atoms and one N atom in a Ψ-octa-hedral PbO(4)NE geometry (E is the electron lone pair). Two longer Pb⋯O inter-actions distort the geometry toward...

The title compound, [Ni(2)(C(9)H(6)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)], is isostructural with the Zn(II) analogue. Each Ni(II) atom is coordinated in a distorted octa-hedral geometry by three O atoms from two homophthalate anions, one aqua O atom and two 1,10-phenanthroline N atoms. The two Ni(II) atoms are linked by two bridging homophthalate dianions into a centrosymmetric dinuclear unit. T...

The cyclo-hexane-1,3-dicarboxyl-ate dianion in the dinuclear centrosymmetric title compound, [Zn(2)(C(8)H(10)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)], has a chair conformation with both carboxyl-ate groups in equatorial positions. One carboxyl-ate group chelates a Zn(II) atom, whereas the other binds through one O atom only to confer a six-coordinate status to the N-heterocycle-chelated water-coor...
