Crystal structure of tetra-kis-(?-N-phenyl-acetamidato)-?(4) N:O;?(4) O:N-bis-[(2-methyl-benzo-nitrile-?N)rhodium(II)](Rh-Rh).

ABSTRACT: The complex molecule of the title compound, [Rh2{N(C6H5)COCH3}4(C8H7N)2], exhibits inversion symmetry. The four acetamidate ligands bridging the dirhodium core are arranged in a 2,2-trans manner with two N atoms and two O atoms coordinating to each Rh(II) atom trans to one another. The Neq-Rh-Rh-Oeq torsion angles on the acetamidate bridge vary between -4.07?(5) and -6.78?(7)°. The axial nitrile ligands complete the distorted octa-hedral coordination sphere of each Rh(II) atom and show a nonlinear coordination with Rh-N-C bond angles of 151.6?(3) and 152.5?(3)°. The bond lengths of the two nitrile triple bonds are 1.133?(5) and 1.137?(5)?Å.

Tetra-kis[?-N-(2,4,6-trimethyl-phen-yl)acetamidato]-??N:O;??O:N-bis-[(benzo-nitrile-?N)rhodium(II)](Rh-Rh).

Project description:The title structure, [Rh?(C??H??NO)?(C?H?N)?], contains a dinuclear Rh complex of point symmetry -4 with an Rh-Rh unit and two benzonitrile ligands located in special positions along the twofold axis passing through -4. Four symmetry-equivalent mesitylacetamidate ligands bridge the Rh-Rh unit. Thus, each Rh(II) atom has an approximately octa-hedral coordination by one Rh [Rh-Rh = 2.4290?(6)?Å], two acetamidate O atoms trans to each other [Rh-O = 2.044?(3)?Å], two acetamidate N atoms trans to each other [Rh-N = 2.091?(4)?Å], and a benzonitrile N atom trans to Rh [Rh-N = 2.222?(3)?Å]. The structure is held together by weak van der Waals forces.

(3-Methyl-benzo-nitrile-κN)tetra-kis(μ-N-phenyl-acetamidato)-κ(4) N:O;κ(4) O:N-di-rhodium(II)(Rh-Rh).

Project description:In the title compound, [Rh2(C8H8NO)4(C8H7N)], the four acetamidate ligands bridging the dirhodium core are arranged in a 2,2-trans manner. One Rh(II) atom is five-coordinate, in a distorted pyramidal geometry, while the other is six-coord-in-ate, with a disorted octa-hedral geometry. For the six-coord-inate Rh(II) atom, the axial nitrile ligand shows a non-linear Rh-nitrile coordination with an Rh-N-C bond angle of 166.4 (4)° and a nitrile N-C bond length of 1.138 (6) Å. Each unique Rh(II) atom is coordinated by a trans pair of N atoms and a trans pair of O atoms from the four acetamide ligands. The Neq-Rh-Rh-Oeq torsion angles on the acetamide bridge varies between 12.55 (11) and 14.04 (8)°. In the crystal, the 3-methyl-benzo-nitrile ring shows a π-π inter-action with an inversion-related equivalent [inter-planar spacing = 3.360 (6) Å]. A phenyl ring on one of the acetamide ligands also has a face-to-face π-π inter-action with an inversion-related equivalent [inter-planar spacing = 3.416 (5) Å].

Tetra-kis(?-2-phenyl-acetato-?(2) O:O')bis-{[4-(di-methyl-amino)-pyridine-?N (1)]cobalt(II)}.

Project description:The title compound, [Co2(C8H7O2)4(C7H10N2)2], crystallizes as a centrosymmetric dimer containing two Co(II) atoms bridged by four bidentate phenyl-acetate ligands in syn-syn bridging modes. Each Co(II) atom is five-coordinated by four O atoms from four different carboxyl-ate ligands and the ring N atom of a 4-(di-methyl-amino)-pyridine unit, generating a distorted square-pyramidal geometry in which the four O atoms form the basal plane and the N atom occupies the axial position. In the crystal, C-H?O inter-actions link the dinuclear complex mol-ecules into a three-dimensional network.

(Meth-oxy-methyl-idene)di-methyl-aza-nium tetra-phenyl-borate aceto-nitrile monosolvate.

Project description:In the cation of the title salt, C4H10NO(+)·C24H20B(-)·C2H3N, the C-N bond lengths are 1.2864?(16), 1.4651?(17) and 1.4686?(16)?Å, indicating double- and single-bond character, respectively. The C-O bond length of 1.2978?(15)?Å shows double-bond character, pointing towards charge delocalization within the NCO plane of the iminium ion. C-H?? inter-actions are present between the methine H atom and two of the phenyl rings of the tetra-phenyl-borate ion. The latter forms an aromatic pocket in which the cation is embedded. The iminium ion is further connected through a C-H?N hydrogen bond to the aceto-nitrile mol-ecule. This leads to the formation of a two-dimensional supramolecular pattern along the bc plane.

(But-oxy-methyl-idene)di-methyl-aza-nium tetra-phenyl-borate aceto-nitrile monosolvate.

Project description:In the title solvated salt, C7H16NO(+)·C24H20B(-)·C2H3N, the C-N bond lengths in the cation are 1.2831?(19), 1.467?(2) and 1.465?(2)?Å, indicating double- and single-bond character, respectively. The C-O bond length of 1.2950?(18)?Å shows a double-bond character, pointing towards charge delocalization within the NCO plane of the iminium ion. The two C atoms of the n-butyl group are disordered over the two sites, with refined occupancy ratios of 0.890?(5):0.110?(5) and 0.888?(4):0.112?(4). In the crystal, C-H?? inter-actions occur between the methine H atom, H atoms of the -N(CH3)2 and -CH2 groups of the cation, and two of the phenyl rings of the tetra-phenyl-borate anion. The latter inter-action forms an aromatic pocket in which the cation is embedded. Thus, a two-dimensional pattern is created in the ac plane.

Tetra-kis(μ-2-methyl-benzoato)bis-[(2-methyl-benzoic acid)copper(II)].

Project description:In the title centrosymmetric dinuclear compound, [Cu(2)(C(8)H(7)O(2))(4)(C(8)H(8)O(2))(2)], four o-toluate anions form a cage around two Cu atoms in a syn-syn configuration. Two more o-toluic acid mol-ecules are apically bonded to the Cu atoms, which show a square-pyramidal coordination geometry. The acid H atoms are hydrogen bonded to the cage carboxyl O atoms [O⋯O = 2.660 (2) Å]. The mol-ecular packing forms a puckered pseudo-hexa-gonal close-packed layer in the (h00) plane, with soft inter-molecular H⋯H contacts (2.46-2.58 Å).
