ABSTRACT: Two independent diphenyl-tin mol-ecules and two independent methanol mol-ecules comprise the asymmetric unit of the title compound, [Sn(C(6)H(5))(2)(C(17)H(14)N(2)O(3))]·CH(3)OH. The Sn atom in each is five-coordinated by a tridentate ligand and the ipso-C atoms of the Sn-bound benzene substituents. The resulting C(2)N(2)O donor set defines a coordination geometry that is inter-mediate between trigonal-bipyramidal (TP) and square-pyramidal (SP), with one mol-ecule slightly tending towards TP and the other slightly towards SP. The mol-ecules differ in terms of the relative orientations of the terminal benzene rings [dihedral angles = 45.71 (18) and 53.98 (17)°] and of the Sn-bound benzene substituents [dihedral angles = 59.5 (2) and 45.77 (18)°, respectively]. The most prominent feature of the crystal packing is the formation of four-mol-ecule aggregates via O-H⋯O and O-H⋯N hydrogen bonds, in which the hy-droxy group is connected to a methanol mol-ecule which, in turn, is linked to a non-coordinating N atom. Weak C-H⋯π inter-actions also occur.
Project description:The Sn(IV) atom in the title compound, [Sn(CH(3))(2)(C(17)H(14)N(2)O(3))], is five-coordinated within a C(2)N(2)O donor set provided by the N,N,O-tridentate ligand and two methyl groups. The resultant coordination geometry is inter-mediate between trigonal-bipyramidal and square-pyramidal. In the crystal, supra-molecular zigzag chains propagating along the c- axis direction are mediated by O-H?O hydrogen bonds, and weak C-H?? inter-actions consolidate the packing.
Project description:In the title compound, [Sn(C(6)H(5))(2)(C(18)H(12)N(2)O(3))], the Sn(IV) atom has a distorted trigonal-bipyramidal geometry. The Schiff base mol-ecule is coordinated to the Sn(IV) atom in a tridentate fashion via the azomethine N atom, the hydr-oxy O atom and the carbonyl O atom. The complex involves an intra-molecular O-H?N hydrogen bond.
Project description:The title compound, C(20)H(26)N(4)O(2)·CH(3)OH, was prepared by the reaction of 4-diethyl-amino-2-hy-droxy-benzaldehyde with 4-(dimethyl-amino)-benzohydrazide. The dihedral angle between the two benzene rings is 13.6 (3)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal, the hydrazone and methanol mol-ecules are linked through inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, forming chains along a.
Project description:The title compound, [Sn6(C4H9)6(CH3COO)6O6]·C7H8, has one half-toluene mol-ecule and one half-organotin mol-ecule in the asymmetric unit. The latter is situated about an inversion centre and belongs to the class of hexa-meric monoorganooxo-tin carboxyl-ates with a hexa-gonal prismatic or 'drum-like' motif of the central tin-oxygen core. Two Sn3O3 rings in a flat-chair conformation are linked via six Sn-O bonds and six bridging acetate groups. All Sn atoms have approximate octa-hedral coordination geometry. The Sn-O bonds which are trans to the alkyl group are significantly shorter than the others. One butyl group is disordered over two different sites, with occupancies of 0.9:0.1. Very large atomic displacement parameters of the toluene mol-ecule indicate an unresolvable disorder about the twofold axis.
Project description:In the title compound, C(14)H(11)IN(2)O(3)·CH(4)O, the dihedral angle between the benzene rings is 33.2 (3)°. The mol-ecule displays trans and anti conformations about the C=N and N-N bonds, respectively. There is an intra-molecular O-H⋯N(azomethine) hydrogen bond. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds consolidate mol-ecules into a three-dimensional architecture.
Project description:In the title complex, [RhCl(C(44)H(32)OP(2))]·CH(3)OH, the Rh(I) ion is coordinated by a naphthyl group of a partially oxidized 2,2'-bis-(diphenyl-phosphan-yl)-1,1'-binaphthyl (BINAP) ligand in a ?(4) mode, one P atom of the diphenyl-phosphanyl group and one Cl atom. The P=O group does not inter-act with the Rh(I) ion but accepts an O-H?O hydrogen bond from the methanol solvent mol-ecule.
Project description:In the crystal structure of the title complex, [Cr(3)(CH(3)CO(2))(6)(N(3))O(CH(3)OH)(2)]·CH(3)OH, the trinuclear core has a central O atom; two methanol mol-ecules and an azide ion are coordinated to the Cr(III) atoms in the core. The three Cr(III) atoms form vertices of a nearly equilateral triangle. Each of the six acetate carboxyl-ate groups bridges a Cr-O-Cr fragment. In the crystal, the molecules inter-act with methanol solvent mol-ecules through O-H⋯O and O-H⋯N hydrogen bonds, forming a two-dimensional hydrogen-bonded network parallel to (100).
Project description:In the title compound, [Sn(C4H9)2(C15H12N2O4)], the Sn(IV) atom is coordinated by the N, O and O' atoms from the tridentate Schiff base dianion in an overall cis-C2SnNO2 trigonal-bipyramidal geometry. Adjacent mol-ecules are linked by O-H?O hydrogen bonds, forming a chain running along [001].
Project description:The title complex, [Fe(2)(C(20)H(14)N(2)O(2))(2)O]·CH(4)O·2H(2)O, is composed of μ-oxido-bridged ferric 2,2'-[o-phenylene-bis(nitrilo-methylidyne)]diphenolate (salphen) dimers, one methanol mol-ecule and two H(2)O mol-ecules. Each iron(III) ion, surrounded by two coordinating N and O atoms from the salphen ligand and one bridging O atom, shows a five-coordinate square-pyramidal geometry. One of the two solvent water mol-ecules is disordered over three positions with occupancies of 0.44 (1), 0.37 (1) and 0.19 (1).
Project description:In the crystal structure of the title compound, C(15)H(13)BrN(2)O(5)·CH(3)OH, the methanol solvent mol-ecule links symmetry-related mol-ecules through O-H?O and N-H?O hydrogen bonds. Further inter-molecular O-H?O hydrogen bonds link symmetry-related mol-ecules, leading to the formation of a three-dimensional network. Two of the H atoms involved in hydrogen bonding are disordered. The dihedral angle between the rings is 5.64?(14)°.
