The isotypic ternary compounds Ba3[MoN4] and Ba3[WN4] were prepared by reaction of the transition metals with barium (Ba3N2, resp.) under nitrogen. The crystal structures were determined by single crystal X-ray diffraction: Ba3[MoN4] (Ba3[WN4]): Pbca; Z = 8; a = 1083.9(3) pm (1091.8(3) pm), b = 1030.3(3) pm (1037.5(3) pm), c = 1202.9(3) pm (1209.2(4) pm). The structures contain isolated tetrahedral anions [MN4]6- (M = Mo, W) which are arranged in form of slightly distorted hexagonal layers and which are stacked along [010] with the sequence (···AB···). Two of the three Ba atoms are situated between, the third one is placed within the layers of [MN4]-groups. In this way the structures can be derived from the Na3As structure type.

AbstractAlthough thienopyridines attract attention because of their biological activities, they have not been used as ligands in coordination compounds. Thieno[2,3-b]pyridine was prepared by known procedures; by reduction of 2-nitrothiophene, and reaction of the resulting 2-thienyl ammonium salt with malondialdehyde tetramethylacetal in the presence of zinc chloride. The same procedure was used for the preparation of a new derivative, 2-methylthieno[2,3-b]pyridine, starting from 2-methyl-5-nitrothiophene. The thienopyridines were used in the synthesis of coordination compounds. Chlorides, isothiocyanates, acetates, and chloroacetates of copper(II), nickel(II), or cobalt(II) were used as starting salts. The prepared complexes were characterized by elemental analysis and FT IR. Structures of the four complexes were determined by single-crystal X-ray diffraction analysis.

Two novel supported heteropolytungstates, NaH3[CoIII(en)2(OH)SiW11CoIIO39]·9.25H2O 1 (en = ethylenediamine) and [Co(en)2]4[Co4(Hen)2Si2W18O68]·H2en·6H2O 2 have been synthesized and characterized by single-crystal X-ray diffraction, electrochemistry, IR, and thermogravimetry. Compound 1 exhibits an interesting one-dimensional chainlike architecture assembled by bridged sodium ions that support monosubstituted Keggin polyoxoanions. To our knowledge, it represents the first example of a supported structure that consists of monosubstituted Keggin polyoxoanions and a novel interbridged, dinuclear Co metal unit. Compound 2 is constructed from trivacant Keggin polyanions linked through a tetrameric cobalt unit, which coordinates with organonitrogen ligands. Moreover, the sandwich-type polyoxoanions were connected by two [Co(en)2] coordination complexes, respectively, and linked by Co2+ ions into a straight chain.

1D Coordination Polymer

Reaction of a methanolic copper(II) acetate solution with tetrazolyl enol derivatives 2a or 2b leads to the formation of the corresponding lD-coordination polymer 1∞[CuL2] 3a and pseudo 1D-coordination polymer [CuL2]2 3b, respectively. On the contrary, reaction of 2c with methanolic copper(II) acetate solution yields OH-bridged 1D-coordination polymer 1∞[CuL2(MeOH)2 3c. Single-crystal X-ray diffraction of the supramolecular species 3 established unequivocally the structures of the stairlike coordination compounds. Reaction of a methanolic copper(II) acetate solution with amidotetrazole derivative 6 leads to the formation of the lD-coordination polymer 1∞ [CuL2] 7. The structure of 7 has been established by X-ray structure analysis
