The PopClip allows you to mount your phone to your dashboard, refrigerator, bed post, locker, wall, mirror, or any other surface! Your PopSocket will snap right into and out of your PopClip to enable hands-free viewing. Sticks flat to the back of your phone, tablet or case with its rinsable, repositionable gel.For best results, use in conjunction with a phone case.Includes both the PopSocket and PopClip and its cardstock retail packaging.It is standard for the PopClip to come black in this combo.The PopClip adheres to surfaces with a single-use 3M VHB adhesive.Online corrected version: (2006–) 'chelation'. ^ IUPAC, Compendium of Chemical Terminology, 2nd ed.Online corrected version: (2006–) 'µ- (mu) in inorganic nomenclature'.

Stability constants are a quantitative measure to assess the thermodynamic stability of coordination complexes. Polydentate ligands such as hexa- or octadentate ligands tend to bind metal ions more strongly than ligands of lower denticity, primarily due to entropic factors. In general, the stability of a metal complex correlates with the denticity of the ligands, which can be attributed to the chelate effect. They are particularly useful for binding lanthanide ions, which typically have coordination numbers greater than 6. The ligands 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetate (DOTA) and diethylene triamine pentaacetate (DTPA) are octadentate. Ligands of denticity greater than 6 are well known.Hexadentate ligands bind with six atoms, an example being EDTA (although it can bind in a tetradentate manner).Pentadentate ligands bind with five atoms, an example being ethylenediaminetriacetic acid. ![]() ![]() On an octahedral metal these leave two vacant sites opposite each other. Many naturally occurring macrocyclic ligands are tetradentative, an example being the porphyrin in heme. tris(2-aminoethyl)amine, are more constrained, and on octahedra leave two cis sites (adjacent to each other). For octahedral metals, the linear tetradentate trien can bind via three geometries. For different central metal geometries there can be different numbers of isomers depending on the ligand's topology and the geometry of the metal center. Tetradentate ligands bind with four donor atoms, an example being triethylenetetramine (abbreviated trien).Cyclic tridentate ligands such as TACN and 9-ane-S3 bind in a facial manner. 'mer' stands for meridian, where the donor atoms are stretched out around one half of the octahedron. Tridentate ligands usually bind via two kinds of connectivity, called 'mer' and 'fac.' 'fac' stands for facial, the donor atoms are arranged on a triangle around one face of the octahedron. Tridentate ligands bind with three atoms, an example being terpyridine.Structure of the pharmaceutical Oxaliplatin, which features two different bidentate ligands. ![]()
