Abstract

TWO NEW BIBR3 SUPRAMOLECULAR COMPLEXES, [BI(2-BPMP)BR2.06CL0.94] (1) AND [BI(4- H2BPMP)BR4.29CL0.71]·H2O (2) {2-BPMP = N,N’-BIS (2-PYRIDYLMETHYL) PIPERAZINE AND 4-BPMP = N,N’-BIS (4-PYRIDYLMETHYL) PIPERAZINE} WERE PREPARED BY REACTION OF BISMUTH (III) CHLORIDE AND POTASSIUM BROMIDE WITH TWO ORGANIC NITROGEN DONOR BASED LIGANDS UNDER THERMAL GRADIENT CONDITIONS USING THE BRANCHED TUBE METHOD. COMPOUNDS 1-2 WERE STRUCTURALLY CHARACTERIZED BY SINGLE-CRYSTAL X-RAY DIFFRACTION. IN THE MONOMERIC COMPLEX 1 THE BISMUTH ATOMS ARE COORDINATED BY TWO PYRIDYL AND PIPERAZINE NITROGEN ATOMS OF A 2-BPMP LIGAND, AND BY THREE HALOGEN ATOMS. COMPOUND 2 IS ALSO MONOMERIC BUT IS BONDED TO ONLY ONE PYRIDYL NITROGEN ATOM. IN BOTH COMPOUNDS EXTENSIVE HYDROGEN-BONDING INTERACTIONS LEAD TO THE FORMATION OF SUPRAMOLECULAR NETWORKS, IN COMPOUND 2 THE HYDROGEN BONDS ARE AUGMENTED BY P-P STACKING INTERACTIONS. THE THERMAL STABILITIES OF BOTH COMPOUNDS WERE STUDIED BY THERMAL GRAVIMETRIC (TG) AND DIFFERENTIAL THERMAL ANALYSES (DTA). THERMAL DECOMPOSITION OF THE NANO SIZED PARTICLES OF 1,2 IN AIR ATMOSPHERE PRODUCED BIOBR NANOPARTICLES.
