Octa-butylbis[?(2)-4-(diethyl-amino)-benzoato-?O:O']bis-[4-(diethyl-amino)-benzoato-?O]di-?(3)-oxido-tetra-tin(IV).

ABSTRACT: The asymmetric unit of the title complex, [Sn(4)(C(4)H(9))(8)(C(11)H(14)NO(2))(4)O(2)], consists of two crystallographically independent half-mol-ecules. The other halves are generated by crystallographic inversion centers. In each tetra-nuclear mol-ecule, both of the two independent Sn atoms are five-coordinated, with distorted trigonal-bipyramidal SnC(2)O(3) geometries. One Sn atom is coordinated by two butyl groups, one O atom of the benzoate anion and two bridging O atoms, whereas the other Sn atom is coordinated by two butyl groups, two O atoms of the benzoate anions and a bridging O atom. All the butyl groups are equatorial with respect to the SnO(3) trigonal plane. Weak intra-molecular C-H?O hydrogen bonds stabilize the mol-ecular structures. In one mol-ecule, two of the butyl groups and the bridging benzoate anion are each disordered over two positions.

Project description:In the title complex, [Sn(4)(C(4)H(9))(8)(C(7)H(5)N(2)O(4))(4)O(2)], all four Sn(IV) atoms are five-coordinated with distorted trigonal-bipyramidal SnC(2)O(3) geometries. Two Sn(IV) atoms are coordin-ated by two butyl groups, one benzoate O atom and two bridging O atoms, whereas the other two Sn(IV) atoms are coordinated by two butyl groups, two benzoate O atoms and a bridging O atom. All the butyl groups are equatorial with respect to the SnO(3) trigonal plane. In the crystal, mol-ecules are linked into a two-dimensional layer parallel to the ab plane by inter-molecular N-H?O and C-H?O hydrogen bonds and further stabilized by a ?-? inter-action [centroid-centroid distance = 3.6489?(11)?Å]. Intra-molecular N-H?O and C-H?O hydrogen bonds stabilize the mol-ecular structure. Two of the butyl groups are each disordered over two sets of sites with site-occupancy ratios of 0.510?(4):0.490?(4) and 0.860?(5):0.140?(5).

Bis(?(2)-4-amino-3-nitro-benzoato)bis-(4-amino-3-nitro-benzoato)octa-butyldi-?(3)-oxido-tetra-tin(IV).

Project description:The tetranuclear molecules of the title compound, [Sn(4)(C(4)H(9))(8)(C(7)H(5)N(2)O(4))(4)O(2)], reside on a crystallographic inversion center. Both the two independent Sn atoms are five-coordinate, with distorted trigonal-bipyramidal geometries. One Sn atom is coordinated by two O atoms of the carboxyl-ate anions, one bridging O atom and two butyl groups and the other Sn atom is coordinated by an O atom of the carboxyl-ate anion, two bridging O atoms and two butyl groups. All the butyl groups are equatorial with respect to the SnO(3) trigonal plane. The mol-ecular structure is stabilized by intra-molecular N-H?O hydrogen bonds. In the crystal, pairs of inter-molecular bifurcated acceptor N-H?O and C-H?O hydrogen bonds link the mol-ecules into chains along [10]. Weak inter-molecular C-H?? and ?-? inter-actions [centroid-centroid distance = 3.713?(2)?Å] are also observed.

Octa-butyl-bis-(?(2)-2-chloro-5-nitro-benzoato)bis-(2-chloro-5-nitro-benzoato)di-?(3)-oxido-tetra-tin(IV).

Project description:The title complex, [Sn(4)(C(4)H(9))(8)(C(7)H(3)ClNO(4))(4)O(2)], is a cluster formed by a crystallographic inversion center around the central Sn(2)O(2) ring. Both of the two independent Sn atoms are five-coordinated, with distorted trigonal-bipyramidal SnC(2)O(3) geometries. One Sn atom is coordinated by two butyl groups, one O atom of the benzoate anion and two bridging O atoms, whereas the other Sn atom is coordinated by two butyl groups, two O atoms of the benzoate anions and a bridging O atom. The O atoms of the bridging benzoate anion are disordered over two sites with an occupancy ratio of 0.862?(12):0.138?(12). One of the butyl groups coordinated to the Sn(2)O(2) ring is disordered over two sites with an occupancy ratio of 0.780?(8):0.220?(8), whereas both of the two butyl groups coordinated to the other Sn atom are disordered over two sites with occupancy ratios of 0.788?(5):0.212?(5) and 0.827?(10):0.173?(10). All the butyl groups are equatorial with respect to the SnO(3) trigonal plane. In the crystal, complex mol-ecules are stacked down [010] with weak inter-molecular C-H?? inter-actions stabilizing the crystal structure.

Octa-methyl-bis-(μ(2)-2-methyl-benzoato-κO:O')bis-(2-methyl-benzoato-κO)di-μ(3)-oxido-tetra-tin(IV).

Project description:The title compound, [Sn(4)(CH(3))(8)(C(8)H(7)O(2))(4)O(2)], is a distann-oxane derivative of 2-methyl-benzoic acid. The crystal structure is composed of centrosymmetric dimers lying about inversion centres. Both independent Sn atoms adopt distorted trigonal-bipyramidal SnC(2)O(3) coordination geometries with the basal planes consisting of two C-atoms from the methyl groups and a bridging O atom. The Sn-C and Sn-O bond lengths lie in the ranges 2.090 (2)-2.104 (3) and 2.0241 (14)-2.2561 (15) Å, respectively. The central four-membered planar Sn(2)O(2) ring [Sn⋯Sn distance = 3.2993 (2) Å] makes dihedral angles of 5.43 (11) and 59.50 (7)° with the methyl-phenyl groups, which are themselves oriented at a dihedral angle of 61.38 (8)°. Besides weak C-H⋯O and C-H⋯π inter-actions, the packing mainly features van der Waals forces between the mol-ecules.

Octa-kis(2-chloro-benz-yl)di-?(2)-hydroxido-di-?(3)-oxido-bis-(2-phenyl-acetato)tetra-tin(IV).

Project description:The asymmetric unit of the title compound, [Sn(4)(C(7)H(6)Cl)(8)(C(8)H(7)O(2))(2)O(2)(OH)(2)], comprises one-half of the centrosymmetric tin(IV) complex. ?(3)-Oxide and ?(2)-hydroxide bridges link the four five-coordinate Sn(IV) atoms to generate three fused four-membered Sn-O-Sn-O rings in a ladder-like structure. The two endocyclic Sn atoms each bind to two ?(3)-oxide anions and a ?(2)-hydroxide ligand, together with two 2-chloro-benzyl groups. The exocyclic Sn atoms each carry a monodentate phenyl-acetate ligand, two 2-chloro-benzyl groups, and ?(3)-oxide and ?(2)-hydroxide ligands. Both types of Sn atoms adopt a distorted trigonal-bipyramidal coordination geometry. The mol-ecular conformation is stabilized by intra-molecular O-H?O inter-actions involving the ?(2)-hydroxide ligands and the C=O group of the phenyl-acetate ligand.

Di-?(2)-chlorido-dichloridoocta-methyldi-?(3)-oxido-tetra-tin(IV) bis[chloridodimeth-yl(pyrrolidine-1-carbodithio-ato-?(2)S,S')tin(IV)].

Project description:In the title co-crystal, [Sn(4)(CH(3))(8)Cl(4)O(2)]·2[Sn(CH(3))(2)Cl(C(4)H(8)NS(2))], all the Sn(IV) atoms are in distorted trigonal-bipyramidal environments. In the mononuclear species, the carbodithio-ate ligand is unsymmetrically coordinated to the Sn(IV) atom, with Sn-S distances of 2.6722?(12) and 2.4706?(11)?Å. All atoms with the exception of the methyl groups and one of the pyrrolidine ring CH(2) groups lie on a crystallographic mirror plane. The pyrrolidine ring exhibits an envelope conformation; the C atom at the flap is disordered above and below the plane of symmetry with fixed occupation factors of 0.50. The centrosymmetric dimer species consists of a central Sn(2)O(2) unit with two adjacent Sn(2)OCl four-membered rings.

Di-μ(3)-oxido-bis-(μ(2)-quinaldato-κO:O)-bis-(quinaldato-κN,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 μ(3)-O atom and a μ(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).

Project description:In the title compound, (C(5)H(7)N(2))(6)[V(10)O(28)]·2H(2)O, the [V(10)O(28)](6-) anion is generated by crystallographic inversion symmetry and each of the five vanadium centres adopts a distorted VO(6) octa-hedral geometry. In the crystal structure, a network of N-H?O, N-H?(O,O) and O-H?O hydrogen bonds helps to establish the packing.
