In the title compound, [Ir(C11H8N)2(C18H14N)], the IrIII ion adopts a distorted octa-hedral coordination environment defined by three C,N-chelating ligands, one stemming from a 2-(4-phenyl-5-methyl-pyridin-2-yl)phenyl ligand and two from 2-(pyridin-2-yl)phenyl ligands, arranged in a facial manner. The IrIII ion lies almost in the equatorial plane [deviation(More)
In the title compound, {[Ag(C29H25N3)2]NO3·CH3OH·H2O} n , the Ag(I) cation is four-coordinated by two pyridine N atoms and two imidazole N atoms from four individual 4-(1-(5'-isopropyl-[1,1':3',1''-terphen-yl]-2'-yl)-1H-imidazol-2-yl)pyridine (i-pro-pyim) ligands. This gives rise to a highly distorted tetra-hedral geometry with bond angles falling in the(More)
The title compound, C24H16N2O4 [systematic name: 2,6-di-benzyl-pyrrolo-[3,4-f]iso-indole-1,3,5,7(2H,6H)-tetra-one], consists of a central pyromellitic di-imide moiety with terminal benzyl groups at the N-atom positions. The mol-ecule is located about an inversion centre, so the asymmetric unit contains one half-mol-ecule. In the mol-ecule, both terminal(More)
The asymmetric unit of the title compound, {[HgLCl2]·0.5CHCl3} n (L = N-(pyridin-4-ylmeth-yl)pyridin-3-amine, C11H11N3), contains one HgII ion, one bridging L ligand, two chloride ligands and a chloro-form solvent mol-ecule with half-occupancy that is disordered about a crystallographic twofold rotation axis. Each HgII ion is coordinated by two pyridine N(More)
The title compound, C7H13N3O3S [systematic name: (Z)-methyl 2-di-methyl-amino-N-(methyl-carbamo-yloxy)-2-oxoethanimido-thio-ate], is an oxime carbamate acaride, insecticide and nematicide. The asymmetric unit comprises two independent mol-ecules, A and B. The dihedral angles between the mean planes [r.m.s. deviations = 0.0017 (A) and 0.0016 Å (B)] of the(More)
The title salt, C18H26N42+·2Cl-, was obtained by the protonation of N,N-bis-(pyridin-4-ylmeth-yl)cyclo-hexane-1,4-di-amine with hydro-chloric acid in ethanol. The asymmetric unit consists of one half of an N,N-bis-(pyridin-3-ylmeth-yl)cyclo-hexane-1,4-di-ammonium dication, with a crystallographic inversion centre located at the centre of the cyclo-hexyl(More)
Treatment of N,N-bis-(pyridin-4-ylmeth-yl)cyclo-hexane-1,4-di-amine with hydro-chloric acid in ethanol led to the formation of the title salt, C18H26N42+·2Cl-·2H2O, which lies about a crystallographic inversion center at the center of the cyclo-hexyl ring. The asymmetric unit therefore comprises one half of the(More)
In the title compound, [Ir(C11H8N)2(C13H10NO)]·CH2Cl2, the Ir(III) ion is six-coordinated by two C,N-bidentate 2-(pyridin-2-yl)phenyl ligands and one N,O-bidentate 2-[(phenyl-imino)-meth-yl]phenolate anion, giving rise to a distorted octa-hedral environment. The C,N-bidentate ligands, in which the C and N atoms are statistically disordered over two sites(More)
The title compound, K11[α-Pt(μ3-OH)2(μ3-OH0.5)Mo6(μ3-O)3(μ2-O)6O12]2·12H2O (simplified chemical formula K11[H2.5PtMo6O24]2·12H2O), containing the well-known Anderson-type heteropolyoxomolybdate anion, was obtained by hydro-thermal reaction at pH = ca 6.0. The complete polyanion dimer has 2/m symmetry. The locations of the H atoms with respect to protonated(More)
The title compound, (CH6N3)7H9[PtMo6O24]2·7H2O, containing the well-known Anderson-type heteropolyoxomolybdate, was obtained by recrystallization of its powdered guanidinium salt. The protonated O atoms in the polyanion were confirmed by electron-density maps, inter-polyanion hydrogen bonds and bond-valance sums (BVS). The {[H4.5PtMo6O24]2}(7-) polyanion is(More)
