Complex 1 crystallizes in an orthorhombic lattice without
solvates.The acetylenic phenyl ring is perpendicular to the
(N^C^N)Pt plane,and the latter is coplanar with the
ab plane.Infinite PtII···PtII chains exist along the c axis,with
a uniform intermetal contact of 3.383 \2 (shorter than the sum
of van der Waals radii of 3.44 \2) and a Pt-Pt-Pt angle of
172.858.Neighboring molecules are arranged in a staggered
fashion with a torsion angle of 49.48 around the Pt–Pt axis
(Figure 1b).Intermolecular C\2H···p interactions have been
discerned between every two adjacent molecules along the
b axis (Figure 1c),as indicated by a short contact of 2.691 \2
between H15 of the (N^C^N) ligand and acetylenic C19 of
another molecule,and a C15-H15-C19 angle of 159.68.No
short intermolecular contacts could be identified along the
a axis.
Complex 4 crystallizes as thin plates with intrinsic
twinning problems.Nevertheless,we were able to solve the
crystal structure of 4 by direct methods based on a set of X-ray
diffraction data with 87% completeness (see the Supporting
Information for details).The crystal structure has a monoclinic
space group with one half of a hexane solvate molecule
per three crystallographically independent molecules of the
complex.The (N^C^N)Pt planes of the these molecules are
nearly coplanar with the [10\21] crystal faces (see the
Supporting Information for diagrams).The intermetal distances
between the two neighboring molecules are 3.229,
4.879,and 3.710 \2.Similar to crystal 1,the intermolecular
C\2H···p(C\3C) interactions with a short contact distance of2.646 \2 and contact angle of 163.68 have been identified
between every two adjacent molecules along the c axis.
