ABSTRACT In the title complex, [CuCl(2)(C(11)H(17)N(4)O(2))(2)], the Cu(II) ion, lying on an inversion center, is six-coordinated in a distorted octa-hedral [Cu(N(2)O(2)Cl(2))] environment by two N,O-bidentate nitronyl nitroxide radical ligands and two trans-chloride anions. In the imidazoline-1-oxyl-3-oxide unit of the ligand, the four methyl groups and the C atoms to which they are bonded are disordered over two sets of sites, with a refined occupancy ratio of 0.737 (5):0.263 (5).

    ABSTRACT: Transition metal complexes of 6-aminomethyl-bis[methyl-2-(4,5-dihydro-4,4,5,5- tetramethylimidazolinyl-3-oxide-l-oxy)]-2,2'-bipyridine, bpyN(NIT)(2), 1, have been synthesized and characterized by FAB-MS, UV-vis, FT-IR, and EPR spectroscopies, elemental analysis, and susceptibility measurements. Single-crystal X-ray diffraction studies have been performed on all compounds giving the following crystal data: bpyN(NIT)(2), 1, triclinic, P(-)1, Z = 2, a = 10.7224(4) A, b = 11.0995(4) A, c = 13.1134(3) A, alpha = 114.101(9) degrees, beta = 97.476(9) degrees, gamma = 99.667(9) degrees; ZnbpyN(NIT)(2), 2, hexagonal, P3(2), Z = 3, a = 15.4545(3) A, b = 15.4545(3) A, c = 13.5594(3) A; NibpyN(NIT)(2), 3, hexagonal, P3(2), Z = 3, a = 15.2867(1) A, b = 15.2867(1) A, c = 13.7160(1) A; CubpyN(NIT)(2), 4, triclinic, P(-)l, Z = 2, a = 11.8640(4) A, b = 13.2023(4) A, c = 13.2661(5) A, alpha = 90.539(9) degrees, beta = 104.983(9) degrees, gamma = 113.252(9) degrees. The two radicals of the free ligand 1 are almost perpendicular to one another in the solid state, favoring a weak ferromagnetic interaction (J/k(B) = 8.8 K). The complexes obtained by wrapping the ligand around a single metal center gave rise to two different coordination schemes where the two radicals of 1 adopt a ON(3)O meridional (with Ni and Zn) or a ON(3)O facial conformation (with Cu), which strongly affects the magnetic and electronic properties (O accounts for the coordinated oxygen atoms of the nitroxide radicals and N(3) accounts for the tertiary amine). For 2, a model of a dimer has been used giving rise to a weak antiferromagnetic interaction between the radicals (J/k(B) = -5.3 K). For 3, a very strong intramolecular antiferromagnetic coupling has been found and estimated at J/k(B) = -230 K and J'/k(B) = -110 K between the nickel and each radical using an asymmetric model of a trimer. For 4, an unusual magnetic behavior is observed, dominated by antiferromagnetic interactions with a residual plateau at chiT = 0.63 emu.K.mol(-)(1). Molecular modeling at the CASSCF level is in keeping with an antiferromagnetic coupling of the radical bound with the Cu(II) in the equatorial position. The combined structural, electronic, and magnetic characteristics suggest that the use of a flexible molecule provide an additional approach for fine-tuning magnetic interactions.

    ABSTRACT: An account is given of the development of the SHELX system of computer programs from SHELX-76 to the present day. In addition to identifying useful innovations that have come into general use through their implementation in SHELX, a critical analysis is presented of the less-successful features, missed opportunities and desirable improvements for future releases of the software. An attempt is made to understand how a program originally designed for photographic intensity data, punched cards and computers over 10000 times slower than an average modern personal computer has managed to survive for so long. SHELXL is the most widely used program for small-molecule refinement and SHELXS and SHELXD are often employed for structure solution despite the availability of objectively superior programs. SHELXL also finds a niche for the refinement of macromolecules against high-resolution or twinned data; SHELXPRO acts as an interface for macromolecular applications. SHELXC, SHELXD and SHELXE are proving useful for the experimental phasing of macromolecules, especially because they are fast and robust and so are often employed in pipelines for high-throughput phasing. This paper could serve as a general literature citation when one or more of the open-source SHELX programs (and the Bruker AXS version SHELXTL) are employed in the course of a crystal-structure determination.

    ABSTRACT: In the mononuclear title complex, [Co(C(11)H(17)N(4)O(2))(2)(CH(3)OH)(2)](ClO(4))(2), the cobalt(II) atom lies on a symmetry centre and is coordinated by two O,N-bidentate ligands and two trans-arranged O atoms of the methanol mol-ecules in a slightly distorted octa-hedral geometry. In the crystal structure, cations and anions are linked by N-H⋯O and O-H⋯O hydrogen bonds into layers parallel to the bc plane.
