A family of Mn(III) dimers of general formula [Mn(R-sao)2(dpa)2](ClO4)2 (1-5) has been synthesised using derivatised phenolic oximes (R-saoH2, where R = H, Me, Et, Ph) in combination with di-(2-picolyl)-amine (dpa). Their structures reveal a double-oxime bridged [Mn(III)(NO)]2 magnetic core in which the Jahn-Teller axes lie perpendicular to the bridging plane, in contrast to two previously repo...

In the title compound, C(15)H(13)BrN(2)O(2), he oxime unit adopts an E conformation with respect to the O-H group. A classical intra-molecular O-H⋯N hydrogen bond results in the formation of a six-membered ring. The crystal structure is stabilized by inter-molecular O-H⋯N hydrogen bonds between the hydr-oxy groups and the oxime N atoms. In addition, the crystal structure also features short int...

In this work, the effect of ligand's length on interaction energy of six oximes, A [2-(hydroxyimino)-N-((1-(2-(2-((hydroxyimino)methyl)-1H-imidazol-1-yl)ethyl)-1H-1,2,3-triazol-4-yl)methyl)acetamide], B [2-(hydroxyimino)-N-((1-(3-(2-((hydroxyimino)methyl)-1H-imidazol-1-yl)propyl)-1H-1,2,3-triazol-4-yl)methyl)acetamide], C [2-(hydroxyimino)-N-((1-(4-(2-((hydroxyimino)methyl)-1H-imidazol-1-yl)but...

The complete mol-ecule of the title compound, C(10)H(18)N(4)O(2), is generated by a crystallographic inversion centre at the mid-point of the central C-C bond. The two oxime groups have an E configuration. In the crystal, mol-ecules are linked through inter-molecular O-H⋯N hydrogen bonds.

Each mol-ecule of the title compound, C(12)H(18)N(4)O(6), is located on an inversion centre at the mid-point of the central N-N bond. The azo groups C=N of the Schiff base group have an E conformation and the azo groups in the oxime C=N-O groups have a Z conformation. O-H⋯O hydrogen bonds link neighbouring mol-ecules into infinite monolayers perpendicular to the a axis.

In the title compound, C(34)H(35)N(3)O(2), the polysubstituted piperidine ring adopts a chair conformation and the isoxazolidine ring is in an envelope form. The mol-ecules are linked into a chain along the b axis by O-H⋯N, C-H⋯O and C-H⋯N inter-actions. The chains are cross-linked via weak C-H⋯π inter-actions.

A manganese single-chain magnet, [Mn(6)O(2)(4-MeOsalox)(6)(N(3))(2)(MeOH)(4)](n) (4-MeO-H(2)salox = 2-hydroxy-4-methoxybenzaldehyde oxime), is synthesized via the assembly of Mn(6) single-molecule magnets, which exhibits a large magnetic coercivity.

Various 2-substituted indolizines can be directly and selectively lithiated in the 5 position and subsequent reactions with different electrophiles lead to some novel classes of indolizines. In particular, previously unknown 5-formyl- and 5-iodoindolizine have been prepared by this way and the molecular structure of 5-formyl-2- phenylindolizine was confirmed by X-Ray analysis. The reactivity of...

In the title compound, C(16)H(16)N(2)O, the dihedral angle formed by the two benzene rings is 50.3 (1)°. In the crystal structure, mol-ecules are linked into an infinite one-dimensional supra-molecular structure by inter-molecular O-H⋯N hydrogen-bond inter-actions.
