A second crystal form of [Ni(2,2′-bipyridine)(H2O)3(NO3)](NO3) featuring a different molecular orientation
The molecular structure of a second form of [Ni(2,2′-bipyridine)(H2O)3(NO3)](NO3) is reported. The previous report is for a blue monoclinic polymorph. The second form is orthorhombic and crystallises as green blocks with unit cell parameters a = 9.1201(12) Å, b = 14.444(2) Å, c = 21.805(4) Å, V = 28...
