Crystal structures, electronic properties and structural pathways offour [Cu(phen)2Cl][Y] complexes(phen = 1,10-phenanthroline;Y = BF4-·0.5H2O, PF6-,CF3SO3-·H2O orBPh4-)
TL;DR: In this paper, the crystal structures of four chromophore complexes have been determined by X-ray crystallography, and scatterplot analysis of the eight cation distortion isomers of these complexes suggest that all the complexes involve a -A + B route distortion of the======CuN================== 4======Cl chromophores, -A (ca. 60%) and +B======(ca. 40%), the observation of linear and parallel correlations are alternatively interpreted as a direct observation of vibronic connections.

Comparative Crystallography. 5. Crystal Structures, Electronic Properties, and Structural Pathways of Five [Cu(phen)2Br][Y] Complexes, Y = [Br]-·H2O, [ClO4]-, [NO3]-·H2O, [PF6]-, and [BPh4]-
TL;DR: In this paper, the crystal structures of six cation distortion isomers of the [Cu(phen)2Br][Y] series of complexes were determined by X-ray diffraction.

Crystal structures, electronic properties and structural pathways of two[Cu(phen)2(OH2)][Y]2 complexes(phen = 1,10-phenanthroline,Y = CF3SO3- or ClO4-)
TL;DR: The crystal structures of 1 and 2 were determined by Diffractometer data collection and scatterplot analysis, with other complexes involving two-fold axes of symmetry as mentioned in this paper, which suggests the presence of vibronic coupling.

TL;DR: A simple technique to accurately estimate the location of the needle tip in an ultrasound image, using a set of hypoechoic reference markings on the shaft of a 14-gauge needle, with image processing to improve accuracy and minimize error is developed.
