Electric Literature of 499-40-1, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 499-40-1, C12H22O11.

The preparation and crystal structures of Cu(Hdpa)(chp)2 and a new phaseof Cu(dpa)2 [Hdpa=2-(pyridyl-2-amino)-pyridine, Hchp=6-chloro-2-hydroxy pyridine]
The synthesis and crystal structure of Cu(Hdpa)(chp)2 (I) are reported. The copper environment is six coordinate with Hdpa and one of the chp ligands bonding in a chelating fashion. The second pyridine is bound through N, the O atom takes up the sixth coordination site but is also hydrogen bonded to the Hdpa ligand of a second Cu(Hdpa)(chp)2 unit, forming a centrosymmetric dimer. A new (orthorhombic) phase of Cu(dpa)2 (II) has also been found, in which distorted tetrahedral copper(II) complexes are linked through a network of H bonds between the deprotonated dpa ligand and C-H bonds meta- to the pyridyl nitrogen donor.
