The heterobimetallic complexes [FemMnnBPMP(02CCH2CH3)z1(BPh& (11, [FemMn11BPMP(0~CCH3)~l(BPh& (1'), and [FenMnnBPMP(02CCH2CH3)~](BPb) (2), in which BPMP is the anion of 2,6-bis[(bis(2-pyridylmethyl)amino)methyl]-4-methylphenol, were synthesized and characterized by proton NMR, EPR, and magnetization measurements. The high-spin Fe(II1) (S = V2) and high-spin Mn(I1) centers (S = V2) in 1 and 1' a...

The title compound, {[AgSm(C(6)H(4)NO(2))(2)(CH(3)CO(2))(H(2)O)]ClO(4)}(n), is a three-dimensional heterobimetallic complex constructed from a repeating dimeric unit. Only half of the dimeric moiety is found in the asymmetric unit; the unit cell is completed by crystallographic inversion symmetry. The Sm(III) ion is eight-coordinated by four O atoms of four different isonicotinate ligands, thre...

The synthesis, characterization and crystal structures of copper complexes with chelate ligation derived from the compound 2.2′-diphenylglycine (DpgH) are reported. Compounds [CuCl(Dpg)(EtOH)]2 ( 1 ) [(CuBr2)2(Dpg)2Cu(EtOH)4] 2 were found to be low toxicity using against cancerous cell lines (HCT116 HT29) IC50 values for complex lower than that cisplatin, while opposite was observed . These ina...

The two highly flexible ligands 1,1'-bis(4-phospholanobutyl)ferrocene (5a) and 1,1'-bis(5-phospholanopentyl)ferrocene (5b) reacted with [PtCl2(cod)] (cod = 1,5-cyclooctadiene), [AuCl(tht)] (tht = tetrahydrothiophene) and [{RhCl(CO)2}2] to give the respective chelate complexes cis-[PtCl2(5a,b-κ(2)P,P')] (7a,b), [AuCl(5a,b-κ(2)P,P')] (8a,b) and trans-[RhCl(CO)(5b-κ(2)P,P')] (9b). Treatment of 5a,...

Z. Naturforsch. 55 b, 238-242 (2000); received Oktober 10, 1999 IR Data, Chalcogenides, Molybdenum, Tungsten Red-brown crystals of a new bis(thiomolybdate) complex [Me4N]3[(MoOS3)2Ag] were formed at room temperature through the reaction of a solution of [Me4N]2[MoOS3] in MeCN with solid AgCN. They are monoclinic, space group P2i/c with unit cell parameters a = 16.662(9), b = 9.464(3), c = 17.89...

The heterobimetallic metal-organic framework {[(BPDC)PtCl(2)](3)(Gd(H(2)O)(3))(2)}.5H(2)O (BPDC = 2,2'-bipyridine-5,5'-dicarboxylate) has been designed and synthesized by hydrothermal methods. The new coordination polymer contains subunits of (BPDC)PtCl(2) (1) where both N atoms of the BPDC ligand are attached to a square-planar Pt(II) center. The two remaining cis coordination sites at Pt(II) ...
