Crystal structures of two polymorphs for <i>fac</i>-bromido-tricarbon-yl[4-(4-meth-oxy-phen-yl)-2-(pyridin-2-yl)thia-zole-κ² <i>N</i>,<i>N</i>']rhenium(I).

ABSTRACT: Crystallization of the title compound, fac-[ReBr(ppt-OMe)(CO)₃] (ppt-OMe = C₁₅H₁₂N₂OS), from CH₂Cl₂/n-pentane (1:5 v/v) at room temperature gave two polymorphs, which crystallize in monoclinic (P2₁/c; α form) and ortho-rhom-bic (Pna2₁; β form) space groups. The Re^I complex mol-ecules in either polymorph adopt a six-coordinate octa-hedral geometry with three facially-oriented carbonyl ligands, one bromido ligand, and two nitro-gen atoms from one chelating ligand ppt-OMe. In the crystal, both polymorph α and β form di-periodic sheet-like architectures supported by multiple hydrogen bonds. In polymorph α, two types of hydrogen bonds (C-H⋯O)
