In the monomeric dinuclear title complex, [CuSm(C(20)H(22)N(2)O(4))(NO(3))(3)], the four-coordinate Cu(II) ion has a square-planar geometry involving two O atoms and two N atoms of the deprotonated Schiff base ligand. The Sm(III) ion is ten-coordinate, chelated by four O donor atoms of the Schiff base and two O atoms each from three bidentate nitrate groups, one of which is disordered over two ...

One of the two 1,4-dicarboxyl-ate dianions in the title compound, [Mn(2)(C(12)H(6)O(4))(2)(C(19)H(12)N(4))(2)]·C(3)H(7)NO, uses its two carboxyl-ate groups to chelate two N-heterocycle-chelated Mn atoms; the other 1,4-dicarboxyl-ate dianion binds to four such metal centers. The octa-hedrally coordinated Mn atoms are linked through the two dianions into a layer motif; the dimethyl-formamide mol-...

In the title compound, C(6)H(7)ClN(+)·BF(4) (-)·C(12)H(24)O(6), the complete cation is generated by crystallographic mirror symmetry, with two C atoms and the N and Cl atoms lying on the mirror plane. The complete crown ether is also generated by mirror symmetry, as is the anion (in which the B and two F atoms lie on the mirror plane). The -NH(3) (+) group of the cation inserts into the crown-e...

The title compound, Li(3.5)Eu(1.5)(MoO(4))(4), was prepared by solid-state reactions. The fundamental building units of the structure are LiO(4) polyhedra (site symmetry [Formula: see text]), distorted LiO(6) polyhedra and MoO(4) tetra-hedra, which are further inter-connected via corner-sharing O atoms. One site is occupied by both Li and Eu atoms in a substituent disordered manner (0.25:0.75),...

The polymeric title compound, [Ce(C(7)H(3)N(2)O(6))(3)(C(2)H(6)OS)(2)](n), exists as a linear chain along [111] as the three dinitro-benzoate anions each engages in bridging adjacent dimethyl sulfoxide (DMSO) coordinated Ce(III) atoms. The metal atoms are surrounded by eight O atoms in a square-anti-prismatic environment. There are two independent formula units in the asymmetric unit. The S ato...

In the title complex, [CuNd(C(20)H(22)N(2)O(4))(NO(3))(3)], the Cu(II) ion is coordinated in a distorted square-planar environment by two O atoms and two N atoms of a tetra-dentate Schiff base ligand. The Nd(III) ion is ten-coordinated by three bis-chelating nitrate groups and four O atoms of the Schiff base ligand. The atoms of one of the nitrato ligands are disordered over two sets of sites, ...

In the title heteronuclear complex, [CuSm(C(19)H(20)N(2)O(4))(NO(3))(3)(CH(3)COCH(3))], the Cu(II) ion is five-coordinated by two O and two N atoms from the 6,6'-dimeth-oxy-2,2'-[propane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate ligand (L) and by an O atom from the acetone mol-ecule in a square-pyramidal geometry. The Sm(III) ion is ten-coordinated by six O atoms from the three nitrate liga...

In the title compound, [Cu(NO(3))(2)(C(18)H(16)N(2)O(2))(2)](n), the Cu(II) ion lies on an inversion center and is six-coordinated in a Jahn-Teller-distored octa-hedral geometry defined by four N atoms of the pyridine derivative forming a square plane, above and below which are the O atoms of the nitrate anion. The ligand links the metal atoms linto a linear chain running along the a axis. One ...

In the crystal structure of the title compound, [Mo(C(25)H(22)P(2))(C(30)H(34)O(2)P(2)Si)(N(2))(2)]·0.7C(6)H(6), the Mo atoms are coordinated by four P atoms and two N atoms in a distorted octa-hedral mode. The two C atoms of one of the two eth-oxy groups are disordered and were refined using a split model and site-occupation factors of 0.7:0.3. The crystal structure contains a benzene solvent ...

The title compound, C(7)H(15)N(3)P(+)·BF(4) (-) or [PTA-Me][BF(4)], is the N-methyl-ated derivative of the well known water-soluble amino-phosphine 1,3,5-triaza-7-phosphaadamantane (PTA). The asymmetric unit consists of a cage-like cation [PTA-Me](+) and a disordered tetra-fluoro-borate anion; two F atoms are disordered equally over two sites. A network of weak inter-molecular C-H⋯F hydrogen bo...
