Cs₄[IrO₄] crystallizes monocline, C 2/m, with a = 1031.66(8) pm, b = 671.61(4) pm, c = 660.44(6) pm, b? = 108.118(7)° and Z = 2 in the K₄[IrO₄]-type. The structure has been determined by four-circle-diffractometer data (PW 1100 from Phillips, Ag? Kα , graphite) with 841 I₀(hkl) with I ≥ 3s?(F) (from 947 I₀(hkl) out of 3529 measured reflexes).

Thep-xylene molecules sandwich the cesium ion.[K·dibenzo-18-crown-6] [Al_Me6N₃]·1.5(1-methylnaphthalene) crystallizes in the monoclinic space groupP2₁/c witha=14.176(5),b=13.021(5),c=25.324(8) Å, =98.23(4)⁰, and _calc = 1.08 g cm^–3 forZ=4. The finalR value was 0.132 for 1402 observed reflections. One of the 1-methylnaphthalene molecules is disordered about a center of inversion and interacts with the potassium ion. The other solvent molecule is found roughly in layers in the lattice and also exhibits disorder of the methyl substituent.

Synthesis,Spectroscopic Characterization and X-Ray Crystal Structure of the Chloride-Bridged Face-Sharing Bioctahedral Diiridium Complex [HP-t-Bu2Me][Ir2Cl7(P-t-Bu2Me)2], a Possible Precursor of the Complex [Ir(H)(Cl)2(P-t-Bu2Me)2]

Abstract

The reaction of an ethanolic suspension of [NH₄]₂[IrCl₆] and P-t-Bu₂Me, in the presence of HCl for 15h gives [HP-t-Bu₂Me][Ir₂Cl₇(P-t-Bu₂Me)₂], 1, in 13.5% yield. The dinuclear complex 1 was characterized by elemental analyses, IR, ¹H, ³¹P NMR spectroscopy, and single crystal X-ray analysis. However, when the above reaction is continued for 48 h one obtains only [Ir(H)(Cl)₂(P-t-Bu₂Me)₂], 2, in good yield. It is proposed that complex 1 is a reaction intermediate to 2. Crystallographic data for 1 (at 298 K): a = 16.151(3) Å, b = 11.885(2)Å, c = 21.665(4) Å, β = 90.26(2)°, space group P2_1/c (Z=4).

[ReCl₂(NS)(NSCl)(Pyridine)₂], a Thionitrosyl-chlorothionitrene Complex of Rhenium The title compound was obtained by the reaction of pyridine with either [ReCl₃(NSCl)₂POCl₃] or [ReCl₃(NSCl)₂]₂ · (μ-N₂S₂) under the reducing action of dichloromethane. It is slightly soluble in CH₂Cl₂, from which it can be obtained in form of black crystals. The IR spectrum is reported. The crystal structure of [ReCl₂(NS)(NSCl)(Pyridine)₂] was determined by X-ray diffraction (R = 0.027 for 2105 observed reflexions). Crystal data: a = 1551.6, b = 694.9, c = 1513.2 pm, β = 96.50°, space group P2₁/c, Z = 4. In the monomer molecules, each rhenium atom has a distorted octahedral coordination of two cis-chlorine atoms, two cis-nitrogen atoms of the pyridine ligands and two cis-nitrogen atoms of the thionitrosyl and chloro thionitrene ligands. One of the pyridine groups is in trans position to the nearly linear thionitrosyl group (angle ReNS 176°) with distances ReN of 177 pm and NS of 152 pm. However, in the trans position of the chlorothionitrene group (angle ReNS 159°, distances ReN 189 pm, NS 149 pm) a chlorine atom is found.     

Interrupted super framework of the crystal structure of Cs[Be2(PO4)(PO4H)] cesium diberyllium phosphate hydrophosphate

The crystal structure of cesium diberyllium phosphate hydrophosphate Cs[Be₂(PO₄)(PO₄H)] obtained hydrothermally is analyzed. Unit cell parameters are: a = 4.8860(5) ?, b = 10.7330(11) ?, c = 13.0061(15) ?, α = 92.540(10)°, β = 92.451(9)°, γ = 90.948(9)°, space group P . In the structural motif consisting of PO₄ and BeO₄ tetrahedra, Be,P two-link chains and ribbons are distinguished, typical of a short a-translation of ≈4.9 ?. The presence of ternary and terminal O ligands along with bridging ones determines the term interrupted super framework. The group of two Be tetrahedra with a common edge is detected for beryllium phosphates for the first time. Original Russian Text Copyright ? 2009 by V. V. Bakakin, Yu. V. Seretkin, and S. P.

Über Cs2Li2[GeO4]

About Cs₂Li₂[GeO₄] By heating of a well-ground mixture of the binary oxides CsO_0.55, Li₂O and GeO₂ (Cs:Li:Ge=2,6:2,2:1; Ni-tube; 600 °C; 49d) we got single crystals of Cs₂Li₂[GeO₄] for the first time. Cs₂Li₂[GeO₄] is isotypic to Rb₂Li₂[MO₄] [M = Si, Ti, Ge] [2] and Cs₂Li₂[MO₄] (M = Si, Ti) [3]: according to this Cs₂Li₂[GeO₄] crystallizes triclinic, in the spacegroup P1 with a = 968.7(4) pm, b = 586.0(2) pm, c = 571.4(2) pm, α = 92.71(4)°, β = 110.95(3)° and γ = 94.34(4)° (Guinier-Simon data), Z = 2. The structure was determined by four-circle diffractometer data (Ag? K_α ; 2381 I_o(hkl); R = 8,4%; R_w = 5.0%), parameters see text. Further the Madelung Part of Lattice Energy (MAPLE), Effective Coordination Numbers (ECoN) and the Mean Fictive Ionic Radii (MEFIR), have been calculated.     

Synthesis, solid-state structure, and bonding analysis of the beryllocenes [Be(C5Me4H)2], [Be(C5Me5)2], and [Be(C5Me5)(C5Me4H)

The beryllocenes [Be(C(5)Me(4)H)(2)] (1), [Be(C(5)Me(5))(2)] (2), and [Be(C(5)Me(5))(C(5)Me(4)H)] (3) have been prepared from BeCl(2) and the appropriate KCp' reagent in toluene/diethyl ether solvent mixtures. The synthesis of 1 is facile (20 degrees C, overnight), but generation of decamethylberyllocene 2 demands high temperatures (ca. 115 degrees C) and extended reaction times (3-4 days). The mixed-ring beryllocene 3 is obtained when the known [(eta(5)-C(5)Me(5))BeCl] is allowed to react with K[C(5)Me(4)H], once more under somewhat forcing conditions (115 degrees C, 36 h). The structures of the three metallocenes have been determined by low-temperature X-ray studies. Both 1 and 3 present eta5/eta1 geometries of the slip-sandwich type, whereas 2 exhibits an almost regular, ferrocene-like, sandwich structure. In the mixed-ring compound 3, C(5)Me(5) is centrally bound to beryllium and the eta(1)-C(5)Me(4)H ring bonds to the metal through the unique CH carbon atom. This is also the binding mode of the eta(1)-ring of 1. To analyze the nature of the bonding in these molecules, theoretical calculations at different levels of theory have been performed on compounds 2 and 3, and a comparison with the bonding in [Be(C(5)H(5))(2)] has been made. As for the latter molecule, energy differences between the eta5/eta5 and the eta5/eta1 structures of 2 are very small, being of the order of a few kcal mol(-1). Constrained space orbital variations (CSOV) calculations show that the covalent character in the bonding is larger for [Be(C(5)Me(5))(2)] than for [Be(C(5)H(5))(2)] due to larger charge delocalization and to increased polarizability of the C(5)Me(5) fragment.

Gemischtligandkomplexe des Technetiums. XV. Zur Reaktion von [TcNCl2(Me2PhP)3] mit Dialkyldithiocarbamaten und N,N-Dialkylthiocarbamoylbenzamidinen

Mixed-ligand Complexes of Technetium. XV. The Reaction of [TcNCl₂(Me₂PhP)₃] with Dialkyldithiocarbamates and N,N-Dialkylthio-carbamoylbenzamidines [TcN(Cl)(Me₂PhP)₂(Et₂dtc)], [TcN(Me₂PhP)(Et₂dtc)₂], and [TcN(Et₂dtc)₂] can be prepared by stepwise ligand exchange reactions starting from dichlorotris(dimethylphenylphosphine)nitridotechnetium(V), [TcNCl₂(Me₂PhP)₃], and diethyldithiocarbamate. In contrast to this, only one intermediate, [TcN(Cl)(Me₂PhP)₂(HEt₂tcb)], could be isolated during the reaction with N,N-Diethlthiocarbamoylbenzamidine, which yields the bis chelate [TcN(HEt₂tcb)₂]. [TcN(Me₂PhP)(Et₂dtc)₂] crystallizes in the monoclinic space group P2₁/c; a = 17.369(5) Å, b = 15.024(1) Å, c = 9.906(3) Å, β = 76.47(1)º, Z = 4. The phosphine is coordinated equatorially. The multiply bonded nitrogen ligand (Tc? N(1) 1.624(3) Å) strongly labilizes the trans positioned donor atom (distance Tc? S(4) 2.826(1) Å). [TcN(HEt₂tcb)₂] crystallizes in the triclinic space group P1 with a = 9.749(4) Å, b = 11.264(4) Å, c = 12.359(4) Å, α = 75.34(2)º, β = 79.69(2)º, γ = 87.55(2)º, Z = 2. The metal is five-coordinate with the nitrido donor atom occupying the apex of a square pyramid. It's basal plane is formed by the cis-coordinated chelate ligands. The technetium is situated over the basal plane by about 0.6 Å. The Tc?N distane was found to be 1.610(5) Å.

Mixed-Ligand Complexes of Rhenium IV. The Reaction of [ReNCl₂(Me₂PhP)₃] with Dithiocarbamates. X-Ray Crystal Structures of trans-Chloro-dimethyldithiocarbamato-bis(dimethylphenylphosphine) nitridorhenium(V), [ReN(Cl)(Me₂PhP)₂(Me₂dtc)], and Bis(diethyldithiocarbamato)(dimethylphenylphosphine)nitridorhenium(V), [ReN(Cl)(Me₂PhP)(Et₂dtc)₂] [ReNCl₂(Me₂PhP)₃] reacts with dialkyldithiocarbamates, R₂dtc^?, under a stepwise ligand exchange. Final products of these reactions are the well-known [ReN(R₂dtc)₂] bischelates. Intermediatelly, however, complexes of the general formulae [ReN(Cl)(Me₂PhP)₂(R₂dtc)] and [ReN(Me₂PhP)(R₂dtc)₂] can be isolated. Representatives have been structurally characterized. [ReN(Cl)(Me₂PhP)₂(Me₂dtc)] crystallizes monoclinic in the space group P2₁/c, Z = 4. The dimensions of the unit cell are a = 13.071(3); b = 11.622(1); c = 15.667(3) Å; β = 97.09(1)°. The rhenium atom has a distorted octahedral environment; the Re≡N bond length is 1.71(1) Å. The Re? Cl bond distance is markedly lengthened (2.665(2) Å) as a consequence of the strong trans labilizing influence of the coordinated nitrido ligand. [ReN(Me₂PhP)(Et₂dtc)₂] crystallizes monoclinic in the space group P2₁/c, Z = 4, a = 17.262(3); b = 14.915(2); c = 9.888(2); β = 76.35(8)°. The equatorial coordination sphere is occupied by one phosphorus atom and three sulphur atoms. One of the dithiocarbamate ligands is coordinated bidentately; the second one with two distinct Re? S bond lengths. The Re? S(4) distance is 2.7983(2) Å which can be discussed as a weak interaction with the metal.
