ABSTRACT: The title compound, (C(4)H(12)N)(3)[CuMo(2)S(8)]·C(3)H(7)NO, was obtained from the self-assembly of tetra-thio-molybdate, tetra-methyl-ammonium nitrate and cuprous sulfide in dimethyl-formamide (DMF). The asymmetric unit contains three (NMe(4))(+) cations, one [Mo(2)S(8)Cu](3-) anion and one DMF solvent mol-ecule, and no obvious inter-actions are observed between these species. The trinuclear anion can be viewed as fused [MoS(4)Cu](-) units sharing a copper center. The geometric parameters of the trivalent anion are comparable to those reported for other related salts including isomorphous anions, namely (NEt(4))(2)(PPh(4))[Mo(2)S(8)Cu] (a) and (Ph(3)P=N=PPh(3))(2)(NEt(4))[W(2)S(8)Cu]·2CH(3)CN (b). However, the Mo-Cu-Mo angle is found to be 160.24?(3)° for the title salt, while this angle is 162.97?(2)° in (a) and the W-Cu-W angle is 170.3?(2)° in (b), indicating that the largest deviation from linearity is in the title compound.
Project description:The title complex salt, (C8H20N)[ZnCl3(C3H7NO)], contains one [Et4N](+) cation (Et is ethyl) and one [ZnCl3(DMF)](-) anion (DMF is di-methyl-formamide). In the anion, the zinc atom is tetra-hedrally coordinated by a DMF ligand via the O atom and by three terminal Cl atoms. The average Zn-Cl bond length and Cl-Zn-Cl angle are 2.243?(11)?Å and 114?(3)°, respectively.
Project description:The title compound, [Cu(C(5)H(5)N)(2)(C(18)H(15)P)(2)]BF(4), crystallizes as discrete [(PPh(3))(2)(py)(2)Cu](+) cations and [BF(4)](-) anions and is isostructural with the analogous perchlorate salt. The anion is located in close proximity to the pyridine ligands with weak C-H?F inter-actions apparent. The P(2)CuN(2) coordination geometry is pseudo-tetra-hedral, with P-Cu-P and N-Cu-N angles of 116.02?(6) and 101.5?(2)°, respectively.
Project description:In the title Cu(I) compound, [Cu(C6H5N5)(C18H15P)2]BF4, the Cu(I) cation is N,N'-chelated by a 5-(pyridin-2-yl)-1H-tetra-zole ligand and coordinated by two triphenyl-phosphane ligands in a distorted tetra-hedral geometry. The tetra-zole and pyridine rings are essentially coplanar [dihedral angle = 4.1?(3)°]. The tetra-fluoridoborate anion links to the complex cation via an N-H?F hydrogen bond.
Project description:The title complex, [Ag(C(18)H(15)P)(4)]BF(4), was prepared by the reaction of silver(I) tetra-fluorido-borate and triphenyl-phosphane in the presence of 1,2-bis-(pyridin-2-yl)ethyl-ene. The Ag(I) atom is tetra-hedrally coordinated by four P atoms from triphenyl-phosphane (PPh(3)) ligands. Due to symmetry, the tetra-fluorido-borate anion is disordered over three positions (each with one third occupancy). The tetra-fluorido-borate anion does not coordinate to the Ag(I) atom.
Project description:In the title compound, [Cu?Cl?(C??H??N?)](n), the central Cu(II) anion of the macrocyclic complex cation is weakly linked to two Cl atoms of the tetrachloridocuprate anion with Cu-Cl distances of 3.008?(3) and 3.220?(3)?Å, respectively, forming a chain parallel to [10-1]. The geometry of the Cu-macrocyclic complex is distorted octa-hedral with the bridging Cl atoms occupying the axial position at an angle of 173.44?(7)° about the central Cu(II) atom. The tetrachloridocuprate anion adopts a distorted tetra-hedral geometry. In the crystal, the chain is stabilized by intra- and inter-molecular N-H?Cl hydrogen bonds.
Project description:The title compound, (C(8)H(20)N)(2)[Cu(5)(C(7)H(4)NO(3))(4)(C(3)H(7)NO)(2)], abbreviated as (TEA)(2)[Cu(II)(12-MC(Cu(II) ) (N(shi))-4](DMF)(2) [where TEA is tetra-ethyl-ammonium, shi(3-) is salicyl-hydroximate (or N,2-dioxidobenzene-1-carboximidate) and DMF is N,N-dimethyl-formamide], contains five Cu(II) ions. Four of the Cu(II) ions are members of a metallacrown ring (MC), while the fifth Cu(II) is bound in a central cavity. Two of the ring Cu(II) ions are five-coordinate with distorted square-pyramidal geometry. The coordination sphere is composed of two shi(3-) ligands and one DMF mol-ecule. The other two ring Cu(II) ions and the central Cu(II) ion are four-coordinate with square-planar geometry. The coordination spheres of these ions are only composed of shi(3-) ligands. The charge of the [Cu(II)(12-MC(Cu(II) ) (N(shi))-4](2-) unit is balanced by two uncoordinated TEA(+) countercations. The structure shows severe static disorder with the metallacrown, the tetra-ethyl-ammonium cations and the DMF solvent mol-ecule all disordered over each of two mutually exclusive sites, with occupancy rates for the major moieties of 0.6215?(6) for the metallacrown, 0.759?(3) for the tetra-ethyl-ammonium ion and 0.537?(6) for the DMF mol-ecules. The metallacrown unit is located on a crystallographic inversion center and disordered about a non-crystallographic twofold axis. The DMF mol-ecule and the tetra-ethyl-ammonium ion are disordered about a non-crystallographic twofold axis and pseudo-inversion center, respectively.
Project description:The title compound, [Cu(C(12)H(8)N(2))(C(18)H(15)P)(2)](2)[Mo(6)O(19)], was obtained by co-crystallization of the mixed-ligand copper complex cation (1,10-phenanthroline)bis-(triphenyl-phos-phane)copper(I), [Cu(phen)(PPh(3))(2)](+), with the Lindquist polyanion [Mo(6)O(19)](2-). The asymmetric unit consists of half a Lindquist anion and one [Cu(phen)(PPh(3))(2)](+) cationic complex. In the cation, there are intra-molecular ?-? inter-actions [centroid-centroid distances = 3.617?(2) and 3.7272?(18)?Å]. This inorganic-organic adduct is connected by C-H?O hydrogen bonds, forming a two dimensional network lying in the ab plane. These networks are connected by C-H?? inter-actions into a three-dimensional structure.
Project description:The title compound, (C(8)H(20)N)(2)[Cu(2)Mo(2)(C(2)H(4)S(2))(2)(CN)(2)S(4)], is a sulfide-bridged tetranuclear complex in which the complex anion comprises one [(edt)(2)Mo(2)S(2)(?-S)(2)](2-) unit (edt = ethanedithiol-ate) and two CuCN units joined through six Cu-?(3)-S bonds, thus forming a cubane-like [Mo(2)S(4)Cu(2)] core. There are two independent cation-anion complex entities in the asymmetric unit. Bond distances are normal for this type of complex [ranges: Mo-S = 2.193?(2)-2.390?(2); Cu-S = 2.266?(2)-2.470?(2); Cu-C = 1.899?(7)-1.911?(9)?Å]. One of the thiol-ato C atoms is disordered over two sites in a 0.52?(3):0.48?(3) ratio.
Project description:The title compound, [Cu(C(16)H(11)BrN(2))(C(18)H(15)P)(2)]BF(4), is composed of one Cu(I) atom, one 6-(4-bromo-phen-yl)-2,2'-bipyridine (L) ligand, two triphenyl-phosphane mol-ecules and one tetra-fluoridoborate anion. The Cu(I) ion is four-coordinated in a distorted tetra-hedral configuration by two N atoms from L and two P atoms from triphenyl-phosphane ligands. In the L ligand, the two pyridine rings are not coplanar; the mean planes making a dihedral angle of 15.3?(5)°. In the crystal, the ions are linked by weak C-H?F inter-actions.
Project description:The title compound, (C(6)H(11)N(2))(4)[Mo(8)O(26)] or (emim)(4)[?-Mo(8)O(26)] (emim is 1-ethyl-3-methyl-imidazolium), was obtained from the ionic liquid [emim]BF(4). The asymmetric unit contains two [emim](+) cations and one-half of the [?-Mo(8)O(26)](4-) tetra-anion, which occupies a special position on an inversion centre. The ?-[Mo(8)O(26)](4-) tetra-anion features eight distorted MoO(6) coordination octa-hedra linked together through bridging O atoms.
