An Unprecedented Cluster Unit in (BMIm)2[Hf9Cl14H8(AlCl4)6]

Cluster Unit Randomized Trials

Hydrolysis of 2-phenylazophenyltellurium trihalides: isolation of an unprecedented homometallic, discrete heptanuclear organotellurium oxide cluster.

Alkaline hydrolysis of RTeBr(3) (R = 2-phenylazophenyl) gave intramolecularly stabilized homometallic, heptanuclear organotellurium oxide cluster R(6)Te(7)O(11) (4) in good yield.

An unprecedented double-bridging interpenetrating α-Po network based on a new heterometallic cluster {Cu4Mo6}.

A new coordination polymer of polyoxomolybdate, {[Cu(4)(bbp)(5)Mo(6)O(22)]·(H(2)O)(4)}(∞) (bbp = 1,4-bis(benzoimidazol-1-yl)phenyl), has been synthesized under solvothermal reaction, which represents a double-bridging interpenetrating α-Po network based on the bimetallic cluster {Cu(4)Mo(6)}. The thermogravimetric and electrochemical behaviors have also been studied.

An Application of Cluster Analysis Technique in Educational Planning

In this paper an application of the cluster analysis technique in educational planning is demonstrated by means of a developed computer software with some characteristics of an expert system. The main idea is based on the knowledge-based systems which have been applied in group technology. The software is applied to weekly schedules of the courses and professors of the Industrial Engineering De...

A platonic solid templating Archimedean solid: an unprecedented nanometre-sized Ag37 cluster.

The spontaneous formation of discrete spherical nanosized molecules is prevalent in nature, but the authentic structural mimicry of such highly symmetric polyhedra from edge sharing of regular polygons has remained elusive. Here we present a novel ball-shaped {(HNEt3)[Ag37S4(SC6H4(t)Bu)24(CF3COO)6(H2O)12]} cluster () that is assembled via a one-pot process from polymeric {(HNEt3)2[Ag10(SC6H4(t)...
