The title dinuclear copper complex, [Cu(2)(C(15)H(15)N(6)O)Cl(2)(CH(3)OH)(2)]ClO(4), was prepared by the reaction of copper(II) chloride with bis-[1-(2-pyrid-yl)ethyl-idene]carbonohydrazide in the presence of sodium perchlorate in a methanol solution. It features a mono-deprotonated bis-tridentate ligand, which coordinates to two independent Cu(II) ions, one of which is coordinated by pyridyl N...

Energy saving and reduced consumption of key materials such as bearings in high-end equipment can be realized by synthesizing a new lubricating functional additive, copper-doped carbon quantum dot dispersion liquid (Cu-CQDs) via hydrothermal reaction with glycerol, cupric chloride dihydrate, choline raw materials. The influence the containing Cu-CQDs nanoparticles on properties polyethylene gly...

In the title complex, [Cu(C(9)H(6)N(2)O(5))(H(2)O)(2)]·2H(2)O, the Cu(II) atom has a square-pyramidal coordination environment with a tridentate N-(5-nitro-2-oxidobenzyl-idene)glycinate Schiff base ligand and a water mol-ecule in the basal plane. The apical site is occupied by an O atom from another coordinated water mol-ecule. The crystal structure is stabilized by O-H⋯O hydrogen bonds, buildi...

Purpose A major challenge of homeopathic basic research is to develop test systems that yield consistent results. Outcome of plant bioassays is usually based on growth parameters (e.g. germination rate, seedling length, leaf area). We aimed to evaluate the potential of a crystallisation method with additives ("biocrystallisation”) as a complementary outcome measure. The method used is based on ...
