In the title compound, [AgCl(C(24)H(24)N(2))], the terminal phenyl and tetra-methyl-benzene rings [which form a dihedral angle of 87.92 (14)°] make dihedral angles of 59.59 (11) and 83.19 (12)° with respect to the central benzimidazole ring system. The Ag-C and Ag-Cl single-bond lengths are 2.087 (3) and 2.3267 (9) Å. The C-Ag-Cl bond angle is 172.84 (7)°. C-H⋯π inter-actions contribute to the ...
Tricyclo-hexyl-tin cinnamate reacts with 4,4-dimethyl-amino-pyridine hydro-bromide perbromide to form the title compound, [Sn(C(6)H(11))(3)(C(9)H(7)Br(2)O(2))], which exists as a monomeric mol-ecule with the Sn atom in a distorted tetra-hedral C(3)O coordination geometry.
The title compound, [Na(C(16)H(36)BO(4))](n), has a fourfold axis passing through the Na and B atoms which both are bound by four O atoms. The tetra-butoxy-borate anion provides the bridging to form one-dimensional polymers running along [001], just like those found for the tetra-ethoxy-borate structure. The two but-oxy 'tail' atoms are disordered over two conformations in a 0.887 (9):0.113 (9)...
The title compound, [Cu(2)(OH)(2)(C(6)H(16)N(2))(2)(H(2)O)](BF(4))(2), consists of dinuclear centrosymmetric [Cu(2)(OH)(2)(tmen)(2)(H(2)O)](2+) complex cations (tmen = N,N,N',N'-tetra-methyl-ethane-1,2-diamine) and tetra-fluoridoborate anions. In the cation, the Cu(II) atom shows a slightly distorted square-pyramidal coordination geometry provided by a pair of μ-OH(-) anions and by the N atoms ...
In the title compound, [Co(C(13)H(8)F(2)O)(C(3)H(9)P)(3)], the cobalt(0) atom is coordinated by three trimethyl-phosphine ligands and a π-coordinated carbonyl group of the 2,6-difluoro-benzo-phenone ligand in a distorted tetra-hedral geometry. The Co-O and Co-C distances are 1.896 (2) and 2.049 (4) Å, respectively.
In the centrosymmetric title compound, [Er(2)(C(5)H(5))(4)(C(4)H(9)O)(2)], each Er atom is in a distorted tetra-hedral coordination environment, coordinated by two cyclo-penta-dienyl rings and two tert-but-oxy groups, forming a dimeric complex bridged through the tert-but-oxy groups.
In the title complex, [ZnBr(2)(C(12)H(9)BrN(2))], the Zn(II) ion is in a distorted tetra-hedral coordination environment formed by two imine N atoms of the bis-chelating N-heterocyclic ligand and two Br atoms. The dihedral angle between the pyridine and benzene rings is 8.04 (17)°.
The title compound, [Cu(C24H20NP2S2)(C18H15P)2]·CH2Cl2 or [Cu(dppaS2)(PPh3)2]·CH2Cl2, is a neutral mononuclear copper(I) complex bearing an N,N-bis-(di-phenyl-phospho-rothio-yl)amidate (dppaS2-) ligand and two tri-phenyl-phosphane ligands. The molecular structure shows that the two S atoms of the dppaS2- ligand [Cu-S = 2.3462 (9) and 2.3484 (9) Å] and the two P atoms of the two tri-phenyl-phosp...
The title compound, C(12)H(18)N(4)O(2)SSi, was synthesized to be employed in a Julia-Kocieński olefination. In the mol-ecule, the dihedral angle between the phenyl ring and the tetra-zole ring is 41.50 (5)°. The significantly longer Si-C(methyl-ene) bond [1.8786 (13) Å] and the shortened adjacent C-C bond [1.5172 (18) Å], as well as the significant deviation of the corresponding Si-C-C angle [1...
In the title compound, [Zn(C(11)H(9)N(6))(2)](n), the Zn(II) atom lies on an inversion center and is coordinated by four N atoms from four 5-[4-(1H-imidazol-1-ylmeth-yl)phen-yl]tetra-zolate ligands in a distorted tetra-hedral geometry. The ligands bridge the Zn(II) atoms, leading to the formation of a two-dimensional network parallel to (010). The structure is further stabilized by C-H⋯N, C-H⋯π...
