The reaction of barium chloride with 2, 6-pyridinedicarboxylic acid in water led to the formation of a novelpolymeric complex formulated as {[Ba2(Hpydc)2(pydc)(H20)3].H20.(H2pydc)}.(I). The crystal structure of (I)was characterized by single crystal X-ray diffraction method. The complex was crystallized in the monoclinicsystem with space group P2/c, with four molecule in unit-cell, e.g Z=4. The...

Odontomas are the most common type of odontogenic tumors and account for approximately 22% of maxillary odontogenic tumors [1-3]. They are considered to be developmental anomalies rather than true neoplasms [4]. They are generally asymptomatic [1]. The term odontoma was coined by Paul Broca in 1867. The World Health Organization (WHO) 2005 has categorized odontomas based on the histopathologica...

Some new compounds based on bis-benzimidazole moieties have been synthesized and characterized by IR and NMR spectroscopies. The ability of 3a in transition metal cation sensing such as Co2+, Ni2+, Zn2+, Mn2+, Fe2+ and Cu2+ have been investigated by Uv-vis and fluorescence spectroscopy in methanol solvent. The complexation constants and complex stoichiometry of Cu2+ have been determined. The ex...
