A novel Bi (III) coordination compound, [Bi(HQ)(Cl)4]n ((Q = pyridine-4-carbaldehyde thiosemicarbazone), was prepared in this research using a sonochemical technique. SEM, infrared spectroscopy (IR), XRD, and single-crystal X-ray analysis were utilized to analyze the Bi(III) coordination compound. The structure determined using single-crystal X-ray crystallography indicates that the coordination compound is a 1D polymer in solid state and that the coordination number of bismuth (III) ions is six, (BiSCl5), with one S donor from the organic ligand and five Cl donors from anions. It is equipped with a hemidirectional coordination sphere. It is interesting that the ligand has been protonated in the course of the reaction with a Cl- ion balancing the charge. This compound’s supramolecular properties are directed and regulated by weak directional intermolecular interactions. Through π–π stacking interactions, the chains interact with one another, forming a 3D framework. Thermolysis of the compound at 170 °C with oleic acid resulted in the formation of pure phase nanosized Bi (III) oxide. SEM technique was used to examine the morphology and size of the bismuth (III) oxide product produced.

Background: Osteoporosis is characterized by low bone mass and loss of the quality of bone microarchitecture. These changes increase the probability of bone fracture. This study aimed to determine the effect of an empowerment program based on the Health Belief Model (HBM) on the self-efficacy of older adults to prevent osteoporosis. Methods: It was a randomized controlled trial with pre-test, post-test, and follow-up design. The participants were selected by convenient sampling method and randomly assigned to the intervention (n=38) and control (n=38) groups. The data collection tools were the Osteoporosis Self-efficacy Scale (OSEB) and Osteoporosis Health Belief Scale (OHBS). The intervention program was performed over a consecutive 4-week group education, and a 4-week individual follow up. The study questionnaires were completed before, immediately after the last session, and one month after the completion of the study. The obtained data were analyzed by the Chisquare, Independent t-test, and repeated measures ANOVA in SPSS V. 13. Results: There was a significant difference between the groups in terms of the mean scores of OSEB and its subscales (P<0.05) and the OHBS (P<0.05) after the intervention. These differences were not significant in the control group in all domains (P≥0.05) except "perceived barriers of calcium intake" (P=0.04) and "health motivation" (P=0.02). Conclusion: Education based on HBM is effective in promoting self-efficacy and osteoporosis preventing behaviors. Therefore, this kind of education is suggested for older adults to prevent osteoporosis.

In the present research, a novel mercury (II) metal organic coordination compound, [Hg(Q)I2]n (Q = pyridine-4-carbaldehyde thiosemicarbazide) with nano rods shape was prepared applying an ultrasonic manner. The synthesized compound was determined with infrared spectroscopy (IR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). In solid state the coordination polymer takes the appearance of a zig-zag 1D polymer. The coordination number of Hg (II) is four by one sulfur atom of organic ligand and three iodine atoms which two of iodine atoms are coordinated to other repeating units, and one of iodine is unattached. The zig-zag 1D chains interact with neighboring chains via poor interactions, making a 3D supramolecular metal organic polymer.
