Synthesis, structure, and thermal properties of heteroligand coordination compounds ZnL{(i-C4H9)(2)PS2}(2) (L = Phen, 2,2 '-Bipy, or 4,4 '-Bipy). Polymeric structure of [Zn(4,4 '-Bipy){(i-C4H9)(2)PS2}(2)](n)

Volatile heteroligand compounds of Zn(i-Bu2PS2)(2) with Phen, 2,2'-Bipy, an d 4,4'-Bipy were synthesized. The structure of Zn(4,4'-Bipy)(i-Bu2PS2)(2) w as determined from the single-crystal X-ray data (CAD-4 diffractometer, MoK alpha radiation, 2539 reflections. R = 0.0320). The crystals are triclinic: a = 9.090(2); b = 9.465(2), c = 10.179(2) Angstrom; alpha = 93.13(3)degree s, beta = 107.33(3)degrees, gamma = 103.89(3)degrees, V= 804.0(3) Angstrom( 3), Z= 1, rho(calcd) = 1.322 g/cm(3), space group P (1) over bar. The struc ture is formed from linear polymeric chains oriented along the [110] direct ion. The coordination polyhedron of the Zn atom is a distorted octahedron ( 4S + 2N); and the polyhedron of the P atoms is a (2S + 2C) tetrahedron. The study of the thermal properties in air and in vacuo showed that these comp ounds are of interest as precursors for chemical vapor deposition of ZnS fi lms.
