The title complex, systematic name hexakis(μ2-4-tert-butoxy-4-oxobut-2-en-2-olato)-1:2κ9O2,O4:O2;2:3κ9O2,O4:O2-trizinc, [Zn3(C8H13O3)6], synthesized fromtert-butyl acetoacetate and diethylzinc, consists of trinuclear centrosymmetric molecules of an approximateC3isymmetry. The three metal cations are arranged in a linear fashion, with the central ZnIIatom located on a centre of symmetry. All three metal cations exhibit a distorted octahedral coordination geometry. The terminal ZnIIcations are chelated by threetert-butyl acetoacetate ligands and these units are connected to the central ZnIIatom by the bridging enolate O atoms.

Through Diffusion

The title compound [Na3(C11H6NO3)2(C2H3O2)]n, crystallized through diffusion of diethyl ether into methanol as needles. There are three crystallographically independent Na+cations present, each exhibiting a distorted octahedral coordination geometry, two through coordination by five O atoms and one N atom, and one through coordination by six O atoms. A series of intermolecular O...Na and N...Na contacts leads to the formation of chains along thea-axis direction.

The structure of the dinuclear title complex, [Cu2(C10H8N7)2(NO3)2(H2O)2]·2H2O, consists of centrosymmetric dimeric units with a copper–copper separation of 4.0408 (3) Å. The CuIIions in the dimer display a distorted octahedral coordination geometry and are bridged by two triazole rings, forming an approximately planar Cu2N4core (r.m.s. deviation = 0.049 Å). In the crystal, O—H...O, O—H...N and C—H...O hydrogen bonds and π–π interactions link the molecules into a three-dimensional network.

The title complex, [Ni(C12H17N2O2)2], possesses a crystallographically imposed center of symmetry occupied by the NiII ion. Each 2-methoxy-6-[3-(methylamino)propyliminomethyl]phenolate ligand coordinates the Ni atom in a tridentate mode [Ni—O = 2.0356 (18) Å, and Ni—N = 2.048 (2) and 2.184 (2) Å], resulting in a distorted octahedral coordination geometry.

The title complex of formula [Ni(NH2CH3CHCOO)2(H20)2].2H2O has been prepared from nickel(II) chloride in an aqueous solution by adding D-alanine and potassium hydroxide. It has beett crystallized from an aqueous solution and its structure was determined by X-ray structure analysis. The nickel(II) atom adopts distorted octahedral coordination geometry with two bidentate alanine molecules and two water molecules. The complex is neutral and dihydrated. The network crystal structure shows hydrogen bonding between water and amide hydrogens within the lattice, and each fragment of the complex contains two water molecules as hydrated water.

Reaction of the Schiff base ligand (R)-2-(pyrrol-2-ylmethyleneamino)-2′-methoxy-6,6′-dimethyl-1,1′-biphenyl with tetrakis(dimethylamido)vanadium in toluene gives the mononuclear VIVtitle complex, [V(C2H6N)2(C20H19N2O)2]·C7H8, which was isolated as red crystals. The VIVcation is coordinated by two monoanionic bidentate Schiff base ligands and two N atoms of two dimethylamide anions in a VN6distorted octahedral coordination geometry, in which two N atoms from the dimethylamide anions are placed in acis-configuration.

In the title complex, [Mn(C7H2N2O7)(C10H8N2)] n , the MnII atom has a distorted octahedral coordination geometry, defined by two N atoms from the 2,2′-bipyridine ligand and four O atoms from two 3,5-dinitrosalicylate dianions. One carboxylate O atom acts as a bridge between adjacent metal centres to form a one-dimensional chain. The Mn...Mn distance is 4.315 (6) Å. The crystal packing is stabilized by intermolecular C—H...O hydrogen interactions.
