TLDR
The effect of ligand rigidity on the shape of coordination polyhedra in five-coordinated copper(II) complexes is demonstrated by single-crystal X-ray analysis.Abstract:
The title compound, [Cu{N(CN)(2)}(C(12)H(8)N(2))(2)]BF(4), was prepared as part of our study of the shape of coordination polyhedra in five-coordinated copper(II) complexes. Single-crystal X-ray analysis reveals that the structure consists of [Cu{N(CN)(2)}(phen)(2)](+) cations (phen is 1,10-phenanthroline) and BF(4)(-) anions. The Cu centre is five-coordinated in a distorted trigonal bipyramidal manner by four N atoms of two phen ligands and one N atom of a dicyanamide anion, which is coordinated in the equatorial plane at a distance of 1.996 (2) A. The two axial Cu-N(phen) distances have similar values [average 1.994 (6) A] and are shorter than the two equatorial Cu-N(phen) bonds [average 2.09 (6) A]. This work demonstrates the effect of ligand rigidity on the shape of coordination polyhedra in five-coordinated copper(II) complexes.read more

Bis(1,10-phenanthroline-κ2N,N′)(sulfato-O)copper(II) butane-2,3-diol monosolvate
TL;DR: The title compound, [Cu(SO4)(C12H8N2)2]·C4H10O2], is comprised of neutral monomeric complex and butane-2,3-diol solvent molecules and suggests the higher symmetry space group C2/c, but attempts to refine the structure in this space group resulted in an unsatisfactory model and high R and wR values.

TL;DR: The crystal structures of eight new [Cu(dpyam)2(NCO)][Y] complexes have been determined by X-ray crystallography as discussed by the authors, which are consistent with direct observation of the effect of vibronic coupling on the stereochemistries of the complexes, which can range from SBPDTB to TBDSBP.
