Abstract
The molecule 2P2,P:2kappa2P6,P8-bis[tetra-carbonylchromium(0)], has an inversion center that relates the two chromium coordination spheres. Each metal atom is cis-coordinated to two P atoms of the tetraphosphox ane ring to form a four-membered Cr-P-O-P chelate ring. The eight-memb ered phosphoxane heterocycle is a novel twist-boat-twist-boat configur ational isomer of the alternative adamantanoid cage. Average distances are Cr-C 1.869 (3), Cr-P 2.337 (4) and P-O 1.65 (2) angstrom.
