Distorted trigonal bipyramidal geometry

Diffusion of solutions containing zinc chloride and crown ethers can give solid state structure where the zinc ion is coordinated to the crown ether oxygens.718 A five-coordinate zinc is observed with distorted trigonal-bipyramidal geometry bound to a chloride, a water molecule,... 

A tridentate SNO ligand coordinates with a bipyridine to give ((2,2 -bipyridine)[2-(2-mercapto-phenyl)iminophenoxy])zinc. The monomeric complex has a distorted trigonal bipyramidal geometry with a phenolate and a thiolate coordinated. The synthesis was carried out electrochemically from anodic zinc in the presence of a disulfide-linked ligand precursor.867... 

X-Ray structural determinations on [(2,2 6, 2"-terpyridyl)Cd Mn(CO)5 2] and [Hg Mn(CO)5)2] have been reported. The former has distorted trigonal-bipyramidal geometry at the cadmium atom and shows considerable distortion of the octahedral co-ordination around the manganese atoms, and the latter contains a linear Mn—Hg—Mn system, the Mn(CO)5 groups being eclipsed. The complexes [X In Mn(CO)5)3 J (X = Cl or Bf n = 0—2) have been prepared and studied in detail. The indium-manganese bonds are readily... 

Reaction of [Ru04] with H4PHAB] gives the paramagnetic monoxoruthenium(V) complex (NPr°4)[Ru(0)PHAB] (109). It has a i/(Ru=0) stretch at 887 cm X-ray diffraction studies reveal that it has a distorted trigonal bipyramidal geometry, with a Ru=0 distance of 1.702 A. 

The ylides and imides are present as monomers, and the bismuth center adopts a distorted tetrahedral geometry. In contrast, the structural properties of the bismuth oxides vary widely depending on the aryl ligands attached to the bismuth center the oxides exist as hydrates, dimers, or polymers in solution and in the solid state. X-ray structural analysis of an oxide dimer revealed that the bismuth center has a distorted, trigonal bipyramidal geometry with the two oxygen atoms at the apical and equatorial positions [47, 48]. 

A polymeric chain stracture is observed in Iit2ln(pyr) I, (Hpyr = pyrrole n = 2 in the vapour) the distorted trigonal bipyramidal geometry at each indium features equatorial coordination of the ethyl (In C bond lengths are 2.141(5) and 2.143(5) A) and amido... 

The crystal structure of a dimethylgallium salicylaldehyde complex shows it to be dimeric. There is a central Ga202 ring the Ga atoms are five-coordinate with distorted trigonal bipyramidal geometry.579...
