The crystal structure of the title compound has been determined from X-ray intensity data collected on a four-circle diffractometer with a 0-20 scan and graphite-monochromated Mo Ka radiation (20= 62°).( 2h, No. 14), Z=4, with a= 10-721(10), b=9.592(7),The crystals are monoclinic, space group P21/c C s c= 16"440(8) A and fl= 103"19(6) °. Crystal densities are Om= 1"95 and 0c=2.06 g cm -3. The structure was solved by the heavy-atom technique and refined by least-squares procedures to a final value of R = 0.084 and Rw=0.095, based on the 2291 observed reflexions with l>3a(1). The acetylenic bond is perpendicular to the plane of platinum coordination. The Pt-CI distance trans to the triple bond is longer [2.322 (7) IntroductionThis investigation is a part of the study of metalalkyne complexes which have the general formula Pt[Rt R2C(OH)-C-C-C(OH)R1R2]2. In a previous paper (Dubey, I975) the crystal structure of Pt[(CzHs)2C(OH) -C-C-C(OH) (C2Hs)z]2 has been studied (where RI and R2 groups are the same). The present structure was undertaken to determine the geometry of the molecule where R1 is different from R2. ExperimentalYellow prismatic crystals elongated along the a axis were obtained by crystallization of the compound from acetone solution at 0 °. The crystal density measured by flotation is in good agreement with the calculated value. The space group P2Jc was deduced from the systematic absences for hOl, l=2n+l, and 0k0, k= 2n + 1, together with the 2/m Laue symmetry observed photographically. Precise lattice parameters were obtained from a least-squares refinement of the 20, co, Z and ~0 angles of 15 well centred reflexions on a Syntex P1 automatic diffractometer using graphitemonochromated (take-off angle of 12 °) Mo Ke radiation. The crystal selected for X-ray intensity measurement was approximately 0.5 x 0.3 x 0.3 mm (the long axis parallel to the ~o axis). Intensity data were collected (20 < 62 °) at room temperature with the 0/20 scan mode and the reflexions were scanned at between 1° and 24 ° min -1 depending upon the peak intensity. The intensities of two standard reflexions, recorded after every 25 measurements to monitor the crystal stability, re-* Present address: Department of Chemistry-Biology, University of Quebec (Trois-Rivi6res), C.P. 500, Trois Rivi6res G9A 5H7, P.

Out of 5234 measured intensities, 2291 were observed on the basis of 1> 3a(I).A standard deviation was assigned to each reflexion according to the formula:where S is the total counts collected during the scan, B1 and Bz are the number of counts collected for each background, and e is the ratio of scan time to total background time. The raw intensities were corrected for Lorentz and polarization factors and absorption corrections were applied according to the procedure described by Ahmed (1970). The corrected intensities were placed on an approximate absolute scale obtained from a Wilson plot. A summary of crystallographic data is given in Table 1.

The crystal and molecular structure of trans-chloromethylbis(trimethylarsine)platinum(II) hexafluorobut-2-yne has been determined from three dimensional X-ray diffraction data recorded by diffractometric methods. The structure has been refined by full-matrix least-squares methods on Fusing 1156 reflections to an agreement factor R = 0.077. The crystals are monoclinic, space group P2,/c,C:,, with a = 6.803 (8)

“…Thus the hydrogen atoms bend back significantly (9) with a strongly perturbed C-C bond. However, the authors (9) reported a C-C length of 1.354 (15) A compared to 1.37 (3) A obtained by X-ray diffraction (7). These distances are fairly short, but the uncertainties on the bond lengths are relatively great and the values should be interpreted with great care.…”

“…cis and trans) lengths are within one e.s.d. Therefore the difference in length cannot unambiguously be attributed to the truns-influence, since the surroundings of the chlorine atoms are different (7). An older neutron diffraction study (9) indicates that the four hydrogen atoms of the ethylene lie in a plane.…”

Zeise's salt, anhydrous and monohydrate, has been prepared by a new method similar to the original method used by Zeise. The infrared and laser Raman spectra of the anhydrous Zeise's salt together with the infrared spectra of the deutero and bromo analogs, are reported and discussed. The vibrational spectra are interpreted in terms of a cyclopropane-like ring structure, obtained by the insertion of the platinum atom into the double bond.
