چکیده
In the heterometallic title bulky amido complex, [LiNa(C15H21N2Si)2(C6H16N2)], both alkali metal ions are four-coordinated with distorted tetra-hedral geometries. The Li(+) ion is N,N'-chelated by the N-silylated amido ligand, with Li-N = 2.015 (5) and 2.074 (5) Å. The two amido ligands are arranged cis to each other. The mol-ecule exhibits a twofold rotational symmetry operation along the Li-Na axis. The Na(+) ion is coordinated by two N atoms from the tetra-methyl-ethylenediamine ligand [Na-N = 2.553 (4) Å] and shares two amido N atoms from the N-silylated amido ligands with the Li(+) ion. Although the crystal structure contains voids with an approximate volume of 50 Å(3) there is no inclusion of solvent mol-ecules.

The title compound, [Co(C(2)H(8)N(2))(3)][CoMo(CN)(8)(C(2)H(8)N(2))(2)(H(2)O)]·2H(2)O, is isostructural with the Ni(II) analogue. The Mo(IV) atom is coordinated by eight cyanide ligands, one of which forms a bridge to a Co(II) atom that is itself coordinated by two bidentate ethane-1,2-diamine (en) ligands and one water mol-ecule. Another Co(II) complex, coordinated to three bidentate en ligand...

The title dinuclear complex, [Ag2(CN)3(C9H8N2)2], may be considered as an Ag(II) compound with the corresponding metal site coordinated by two bidentate quinolin-8-amine mol-ecules, one cyanide group and one dicyanidoargentate(I) anion, [Ag(CN)2](-). Since this latter ligand contains an Ag(I) atom, the complex should be a class 1 or class 2 mixed-valence compound, according to the Robin-Day cla...

In the mol-ecular structure of the title compound, [Cr(2)Cl(4)(C(26)H(36)N(2))(2)(C(4)H(8)O)]·4.5CH(2)Cl(2), the two Cr(II) centers are bridged by three Cl atoms, forming a dinuclear complex. Each Cr(II) center is coordinated by one chelating bis-(2,6-diisopropyl-phen-yl)ethane-1,2-diimine ligand via both N atoms. An additional chloride ion binds to one chromium center, whereas an additional te...

The mixed bimetallic title compound, [InLi(CH3)2(C7H7O)2(C6H16N2)] or [(tmeda)Li-μ-(4-MeC6H4O)2InMe2] (tmeda is N,N,N',N'-tetra-methyl-ethylenedi-amine), exhibits a four-membered LiO2In ring core via bridging 4-methyl-phenolate groups. The Li and In atoms are in distorted tetra-hedral N2O2 and C2O2 bonding environments, respectively. The Li atom is further chelated by a tmeda group, yielding a ...
