Di-?-oxido-bis-[bis-(diiso-propyl-aceta-midinato)-?N;?(2) N,N'-germanium(IV)].

ABSTRACT: The title compound, [Ge2(C8H17N2)4O2], crystallizes with imposed twofold symmetry, which allows the monodentate amidinate ligands to be arranged in a cisoid fashion. The independent Ge-O distances within the central Ge2O2 ring, which is essentially planar (r.m.s. deviation = 0.039?Å), are 1.7797?(8) and 1.8568?(8)?Å. The germanium centres adopt a distorted trigonal-bipyramidal geometry, being coordinated by the two O atoms and by one bidentate and one monodentate amidinate ligand (three N atoms). One N-isopropyl group is disordered over two positions; these are mutually exclusive because of 'collisions' between symmetry-equivalent methyl groups and thus each has 0.5 occupancy.

Di-?-thio-cyanato-bis-{[1,2-bis-(diiso-propyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane]silver(I)}.

Project description:The title compound, [Ag(2)(NCS)(2)(C(14)H(38)B(10)P(2))(2)], was synthesized by the reaction of 1,2-bis-(diiso-propyl-phos-phan-yl)-1,2-dicarba-closo-dodeca-borane with AgSCN. The diisopropyl-phosphanyl-closo-carborane ligand is coordinated in a bidentate manner to the Ag(I) atom through the two P atoms. The coordination of the Ag(I) atom is distorted tetra-hedral, in which two vertices are formed by the P atoms of the chelating diphosphine ligand, and the other two are occupied by the S and N atoms of the two bridging thio-cyanate anions, leading to a centrosymmetric binuclear complex. The distance between the two C atoms in the carborane skeleton is 1.851?(6)?Å.

Crystal structure of di-?-iodido-bis-{[1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene]lithium}.

Project description:In the title binuclear complex, [Li2(C27H36N2)2I2], the unique Li(I) cation is coordinated by two iodide anions and one yl-idene C atom from a 1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene ligand in a distorted trigonal-planar geometry. The two symmetry-related iodide anions bridge two Li(I) cations, forming an inversion dimer in which the Li2I2 plane is nearly perpendicular to the imidazol-2-yl-idene ring, with a dihedral angle of 85.5?(3)°. No hydrogen bonding is observed in the crystal.

Crystal structure of N,N'-bis-(diiso-propyl-phosphan-yl)-4-methyl-pyridine-2,6-di-amine.

Project description:In the mol-ecule of the title compound, C18H35N3P2, the methyl-pyridine-2,6-di-amine moiety is almost planar, with a maximum deviation of 0.0129?(9)?Å for one of the amine N atoms. Whereas one of the P atoms is co-planar with this mean plane [deviation = 0.0158?(10)?Å], the other P atom is considerably displaced out of the mean plane by 0.5882?(10)?Å. In the crystal, no directional intermolecular interactions beyond van der Waals contacts could be identified.

Di-?(3)-oxido-di-?(2)-oxido-tetra-oxido-bis-(1,1,2,2-tetra-methyl-ethylenedicyclo-penta-dien-yl)-dimolyb-denum(IV)-dimolybdenum(VI) hexa-hydrate.

Project description:The title compound, [Mo(4)(C(16)H(20))(2)O(8)]·6H(2)O, is a centrosymmetric ansa-molybdocene complex in which two dinuclear [C(2)Me(4)(?(5)-C(5)H(4))(2)]Mo(?(2)-O)(2)MoO(2) units dimerize by forming two ?(3)-O bridges between three Mo atoms. The ansa-molybdocene [C(2)Me(4)(?(5)-C(5)H(4))(2)]Mo unit has a typical bent-sandwich metallocene structure with an inter-ring angle of 127.98?(8)°. The Mo atom in the bridging (?(2)-O)(?(3)-O)(2)MoO(2) group has a distorted trigonal-bipyramidal coordination. The Mo-(?(3)-O) and Mo-(?(2)-O) bond distances inside the units [2.0869?(14) and 2.1014?(15)?Å, respectively] are slightly longer than the Mo(-x + 1, -y + 1, -z)-(?(3)-O) bond distance between the units [1.9986?(14)?Å]. The solvent water mol-ecules together with complex O atoms form a network of O-H?O hydrogen bonds.

Crystal structure of 2-azido-1,3-bis-(2,6-diiso-propyl-phen-yl)-1,3,2-di-aza-phospho-lidine.

Project description:The title compound, C26H38N5P, was synthesized by reacting 2-chloro-1,3-bis-(2,6-diiso-propyl-phen-yl)-1,3,2-di-aza-phospho-lidine with sodium azide and a catalytic amount of lithium chloride in tetra-hydro-furan. The title compound is the first structurally characterized 2-azido-1,3,2-di-aza-phospho-lidine and exhibits a P atom in a trigonal pyramidal geometry. The azide P-N bond length of 1.8547?(16)?Å is significantly longer than the P-N separations for the chelating di-amine [P-N = 1.6680?(15) and 1.6684?(14)?Å]. The sterically hindered 2,6-diiso-propyl-phenyl groups twist away from the central heterocycle, with dihedral angles between the central heteocyclic ring and benzene rings of 76.17?(10) and 79.74?(9)°. In the crystal, a weak C-H?N link to the terminal N atom of the azide group leads to [100] chains.

Di-?(3)-oxido-bis-(?(2)-quinaldato-?O:O)-bis-(quinaldato-?N,O)tetra-kis[di-n-butyl-tin(IV)].

Project description:The title tetra-nuclear Sn(IV) complex, [Sn(4)(C(4)H(9))(8)(C(10)H(6)NO(2))(4)O(2)], is a cluster built up by inversion symmetry around the central Sn(2)O(2) ring. The coordination geometries of the Sn atoms involved can be classified into two types: the five-coordinate Sn atoms of the central Sn(2)O(2) core have a trigonal-bipyramidal geometry, with axial positions occupied by a ?(3)-O atom and a ?(2)-O atom belonging to the nonchelating quinaldate ligand. The peripheral Sn atoms are six-coordinate, with a distorted octa-hedral geometry. The methyl group of an n-butyl ligand is disordered over two sites, with occupancies of 0.643?(12) and 0.357?(12).

Crystal structure of 2-chloro-1,3-bis-(2,6-diiso-propyl-phen-yl)-1,3,2-di-aza-phospho-lidine 2-oxide.

Project description:The title compound, C26H38ClN2OP, was synthesized by reacting phosphoryl chloride with N,N'-bis-(2,6-diiso-propyl-phen-yl)ethane-1,2-di-amine in the presence of N-methyl-morpholine which acted as an auxilliary base to quench the HCl released as a by-product. The resultant N-heterocyclic phosphine five-membered ring adopts a half-chair conformation and features a tetra-coordinate P atom ligated by the chelating di-amine [P-N = 1.6348 (14) and 1.6192 (14) Å], one double-bonded O atom [P1-O1 = 1.4652 (12) Å] and one Cl atom [P1-Cl1 = 2.0592 (7) Å]. The sterically hindered 2,6-diiso-propyl-phenyl (Dipp) groups twist away from the central heterocycle, with torsion angles of -75.66 (19) and 83.39 (19)° for the P-N-Car-Car links. A number of intra-molecular C-H⋯N, C-H⋯O and C-H⋯Cl close contacts occur. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds to generate [010] chains. C-H⋯π inter-actions are also observed.

Crystal structure of bis-(diiso-propyl-ammonium) molybdate.

Project description:The organic-inorganic title salt, (C6H16N)2[MoO4] or ( i Pr2NH2)2[MoO4], was obtained by reacting MoO3 with diiso-propyl-amine in a 1:2 molar ratio in water. The molybdate anion is located on a twofold rotation axis and exhibits a slightly distorted tetra-hedral configuration. In the crystal structure, the diiso-propyl-ammmonium ( i Pr2NH2)+ cations and [MoO4]2- anions are linked to each other through N-H?O hydrogen bonds, generating rings with R 12 12(36) motifs that give rise to the formation of a three-dimensional network. The structure was refined taking into account inversion twinning (ratio of ca 4:1 between the two domains).
