10pin (2x5) header for I2C pinout?

I'm putting together a PCB and would like to add a 2x5 pin header for I2C & power communication. It's easy to find / make 10 pin ribbon cables.
Here's the pinout I'm planning to use, but is there a common pinout for I2C over a 2x5 header?

I2C 5x2 header power 5V & I2C bus

1 SCL
2 GND
3 SDA
4 5V
5 IRQ Open Collector
6 5V
7 5V
8 GND
9 GND
10 GND

I don't remember where I picked this up from but it was on a schematic for a SD card interface.

gnd-----1 2-----gnd
3.3------3 4-----3.3
5--------5 6-----5
SDCS---7 8-----SDCS
MOSI---9 10-----MOSI
SCK----11 12----SCK
MISO--13 14----MISO
gnd----15 16-----gnd

it was using a 2x8 header.
