The synthesis and structural characterization of the complex [Ru2(μ-Cl)(μ-P Bu2)(μ-dppa)(CO)4] (4, dppa = Ph2PN(H)PPh2) are reported. The title compound and two other related complexes were obtained in high yields by the reaction of the coordinatively unsaturated species [Ru2(μ-H)(μ-P Bu2)(μ-PˆP)(CO)4] (PˆP = dppa, 3; PˆP = Ph2PN(Ph)PPh2, 5; PˆP = Ph2PN(CH2Ph)PPh2, 6) with carbon tetrachloride....

With the intention of producing the most comprehensive treatment of the prevalence of crystal polymorphism among structurally characterized materials, all polymorphic compounds flagged as such within the Cambridge Structural Database (CSD) are analysed and a list of crystallographically characterized organic polymorphic compounds is assembled. Classifying these structures into subclasses of anh...

seismic performance and loss assessment studies for stock of buildings are generally based on representative models due to extremely large number of vulnerable buildings. the main problem is the proper reflection of the building stock characteristics well enough by limited number of representative models. this study aims to provide statistical information of structural parameters of turkish bui...
