Abstract The reaction is effective for the aromatic zinc derivatives bearing electron-withdrawing substituents, while poor yields are observed for the electron-donating and unsubstituted substrates [cf. [source]

(Acetato-,O)[tris(3,5-dimethylpyrazol-1-yl-,N2)hydroborato]zinc(II)

ACTA CRYSTALLOGRAPHICA SECTION C, Issue 8 2009
Azizolla Beheshti
The title complex, [Zn(C15H22BN6)(C2H3O2)] or (TpMe,Me)Zn(OAc), contains a tripodal tris(pyrazolyl)hydroborate ligand, a monodentate acetate ligand and a ZnII centre in a distorted tetrahedral coordination environment capped on one triangular face by a secondary Zn...O interaction with the second O atom of the acetate ligand. The four-coordination of ZnII and the essentially monodentate character of the acetate ligand are due to the high steric demands of the ligand set, which prevent chelate formation and five-coordination and lead to relatively long Zn,O and Zn,N bonds compared with related complexes of ZnII and other metals.

cis,cis,cis -(Acetato- O,O,)­bis­[1,2-bis­(di­phenyl­phosphino)­ethane- P,P,]­ruthenium(II) hexa­fluoro­phosphate di­methanol solvate

In the cation of the title complex, cis,cis,cis -[Ru(,2 -O2CMe)(dppe)2]PF6·2MeOH [dppe is 1,2-bis­(di­phenyl­phosphino)­ethane, C26H24P2], the Ru atom is in a pseudo-octahedral coordination environment with two chelating dppe ligands and one chelating acetate ligand. Intra-phosphine and intra-acetate bond lengths and angles are unexceptional. Deviations from idealized octahedral coordination angles at ruthenium [O,Ru,O 59.43,(8)° and P,Ru,P 103.19,(2)°] presumably derive from constraints imposed by the chelate rings. The Ru,P distances for the mutually trans P-donor atoms [2.3785,(6),Å] are significantly longer than those for the Ru,P linkages trans to the acetate ligand [2.3074,(6),Å]. The Ru1, C1 and C2 atoms lie on a twofold axis, and atom P3 of the anion lies on an inversion centre. [source]

A novel trinuclear zinc(II) cluster with a tetrahedral ZnO4 core

The reaction of 0.67 molar equivalents of the O,N,O,-tridentate zwitterionic Schiff base (2Z,4E)-4-[(2-hydroxyphenyl)iminio]pent-2-en-2-olate (H2L) with one equivalent of zinc(II) acetate in methanol affords a novel trinuclear ZnII cluster, di-,-acetato-1:2,2O:O,;2:3,2O:O,-dimethanol-1,O,3,O -bis{,-2-[(2E,3Z)-4-oxidopent-3-en-2-ylideneamino]phenolato}-1:2,4O2,N,O4:O4;2:3,4O4:O2,N,O4 -trizinc(II), [Zn3(C11H11NO2)2(C2H3O2)2(CH4O)2], (I), in which two bridging acetate ligands link the terminal square-based pyramidal ZnII ions to the approximately tetrahedral ZnII ion at the core of the cluster. The ZnO4 coordination group of the central ZnII ion is established by two bridging phenolate and two bridging acetate O atoms. The remaining four coordination sites of each terminal ZnII ion are occupied by methanol and deprotonated H2L. Furthermore, the Zn-bound methanol hydroxyl groups are involved in complementary hydrogen bonding with the Zn-bound enolate O atom of a neighbouring molecule, about an inversion centre in each case. The structure of (I) is therefore best described as an extended one-dimensional hydrogen-bonded chain of trinuclear ZnII clusters. [source]

[Ba6(C2H3O2)12(H2O)3.5], a new hydrate of barium acetate

A new barium acetate phase, di-,5 -acetato-tri-,4 -acetato-tri-,3 -acetato-tri-,2 -acetato-,2 -acetato-triaquahemiaquahexabarium(II), of analytical formula [Ba6(C2H3O2)12(H2O)3.5], is described. The asymmetric unit contains six independent Ba centres with coordination numbers varying from 7 to 10 arising from bonding to 12 crystallographically independent acetate ligands and four molecules of water, one of which is disordered over two sites both of occupancy 0.5. Bonding to the acetate ligands creates a completely connected three-dimensional structure. All H atoms of the water molecules participate in hydrogen bonding. [source]
