چکیده

The title compound, [Hg2Cl4(C26H54B10P2)], was synthesized by the reaction of 1,2-bis-(di-cyclo-hexyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane with HgCl2. Both Hg(II) atoms show a distorted tetra-hedral coordination geometry, provided by the two bridging chloride anions and the P atoms of the diphosphanyl ligand for one metal atom, and by two bridging and two terminal chloride anions for the other. The five-membered HgP2C2 chelate ring assumes an envelope conformation, with the Hg(II) atom displaced by 0.1650 (5) Å from the mean plane of the other four atoms (r.m.s. deviation = 0.002 Å). In the crystal, B-H⋯Cl interactions link the molecules, forming a supramolecular chain along the a-axis direction.

In the title compound, [FeLi(C(29)H(41)N(2))Cl(2)(C(4)H(10)O(2))(2)], the Fe(II) atom is coordinated by two N and two Cl atoms, generating a distorted FeN(2)Cl(2) tetra-hedral geometry. Additionally, one of the chloride atoms bridges to a lithium ion, which is solvated by two dimethoxy-ethane mol-ecules and is coordinated in a distorted trigonal-bipyramidal environment. The central Fe, Cl (× 2)...

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...
