Öğe 1,4-diferrocenylbutane-1,4-dione(Blackwell Publishing, 2008) Tombul, Mustafa; Bulut, Adnan; Guven, Kutalmis; Buyukgungor, OrhanIn the crystal structure of the title compound, [Fe-2(C5H5)(2)-(C14H12O2)], each carbonyl group is coplanar with the adjacent cyclopentadienyl ring, thus maximizing the pi-orbital overlap and electronic interactions between the groups. In the crystal structure, there are inter-and intramolecular C-H center dot center dot center dot O contacts.Öğe Dimethyl trans-3-(4-bromophenyl)-2-methylisoxazolidine-4,5-dicarboxylate(Wiley-Blackwell, 2009) Buyukgungor, Orhan; Yavuz, Serkan; Odabasoglu, Mustafa; Ozkan, Hamdi; Pamir, Ozguer; Yildirir, YilmazIn the title compound, C14H16BrNO5, the isoxazolidine ring adopts an envelope conformation, with the N atom at the flap. In the crystal, intermolecular C-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds generate R-3(3)(18) ring motifs which are fused into a ribbon-like structure extending along the b axis.Öğe Poly[[diaquacaesium(II)]bis(μ3-3-carboxypyrazine-2-carboxylato)]. Corrigendum(Blackwell Publishing, 2008) Tombul, Mustafa; Guven, Kutalmis; Buyukgungor, Orhan…Öğe Poly[triaquabis-(μ(2)-3-carboxy-pyrazine-2-carboxyl-ato)dilithium(I)](Blackwell Publishing, 2008) Tombul, Mustafa; Guven, Kutalmis; Buyukgungor, OrhanIn the title compound, [Li-2(C6H3N2O4)(2)(H2O)(3)](n), the coordination number for both independent Li+ cations is five. One of the Li+ ions has a distorted trigonal-bipyramidal geometry, coordinated by one of the carboxyl O atoms of a 3-carboxypyrazine-2-carboxylate ligand, two O atoms from two water molecules, and an N and a carboxylate O atom of a second 3-carboxypyrazine-2-carboxylate ligand. The other Li+ ion also has a distorted trigonal-bipyramidal geometry, coordinated by one water molecule and two 3-carboxypyrazine-2-carboxylate ligands through an N and a carboxylate O atom from each. One of the carboxyl groups of the two ligands takes part in an intramolecular O-H center dot center dot center dot O hydrogen bond. The stabilization of the crystal structure is further assisted by O-H center dot center dot center dot O, O-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen-bonding interactions involving the water molecules and carboxylate O atoms.
